Calendar
You are encouraged to solve this task according to the task description, using any language you may know.
Create a routine that will generate a text calendar for any year. Test the calendar by generating a calendar for the year 1969, on a device of the time. Choose one of the following devices:
- A line printer with a width of 132 characters.
- An IBM 3278 model 4 terminal (80×43 display with accented characters). Target formatting the months of the year to fit nicely across the 80 character width screen. Restrict number of lines in test output to 43.
(Ideally, the program will generate well-formatted calendars for any page width from 20 characters up.)
Kudos (κῦδος) for routines that also transition from Julian to Gregorian calendar.
This task is inspired by Real Programmers Don't Use PASCAL by Ed Post, Datamation, volume 29 number 7, July 1983.
THE REAL PROGRAMMER'S NATURAL HABITAT "Taped to the wall is a line-printer Snoopy calender for the year 1969."
For further Kudos see task CALENDAR, where all code is to be in UPPERCASE.
For economy of size, do not actually include Snoopy generation in either the code or the output, instead just output a place-holder.

ALGOL W
which is a
This is pretty much the same as the Simula version.
The main differences are that the "for" loop counter in Algol W is a separate variable that only exists during execution of the loop
whereas in Simula the loop counter must be declared outside the loop and has its value changed as the loop executes
- hence some of the "for" loops have been replaced by "while" loops.
In Algol W, the condition of a "while" loop can be a block and the boolean "and" operator short circuits, which allow us to avoid the goto statements.
Also, the Algol W string type is fixed length, unlike the Simula text type.

Amazing Hopper
Hopper tiene una función que genera calendarios en español, y con un formato diferente al pedido.
El calendario generado en un array 2D como el que se muestra a continuación:
Línea de código:
Let ( calendario := Calendar(1,año,12) ) [ 1:8, 1:7 ] Cget 'calendario', Print this table
ENE, , , , , ,1969 Dom,Lun,Mar,Mie,Jue,Vie,Sab , , , 1, 2, 3, 4 5, 6, 7, 8, 9, 10, 11 12, 13, 14, 15, 16, 17, 18 19, 20, 21, 22, 23, 24, 25 26, 27, 28, 29, 30, 31, , , , , , ,
Son generados tantos calendarios como se pida, y de diferentes formas (lineales o radiales). El código a continuación debe reformatear el calendario antes de imprimirlo.

This is quite closely based on the C sample, although the centering calculation has been adjusted to fix an off-by-one error, and the months have been made a constant height, regardless of how much space they require, to try and produce a more balanced layout.
The year is read from stdin, and the width is specified by the first value on the stack (set to 80 - "P" - in the current implementation).

C#
An attempt to abuse the DateTime class for all static information. In the event that the number of days and months changes, so long as the DateTime class is updated accordingly, this should still print properly. It also abuses iterators to allow for a concise month printing method, but with the ability to still print x months per line.

Fortran
Already having a routine to produce a calendar simplified matters. However, it added to each row of days a row of annotations for those days (Xmas, etc. and also +2hh and -2hh for the days with two half-hour changes in length due to daylight saving: NZ also had daylight saving with changes of one half-hour) which meant that the field allowance was always four. With the annotations abandoned, this could be reduced to three, and, the first day column on a line does not need a leading space. Since the method employed variables for the layout, it could easily be twiddled to have three months per line (thus fitting into a line length of 80) or six (using most of a line length of 132) and so it became a matter of pulling together the needed routines from various places.

Can't DO WHILE (L.GT.0 .AND. TEXT(L:L).LE.' ') !Control chars. regarded as spaces.
Curse the morons who think it good that the compiler MIGHT evaluate logical expressions fully.
Crude GO TO rather than a DO-loop, because compilers use a loop counter as well as updating the index variable.
Comparison runs of GNASH showed a saving of ~3% in its mass-data reading through the avoidance of DO in LSTNB alone.
Crappy code for character comparison of varying lengths is avoided by using ICHAR which is for single characters only.
Checking the indexing of CHARACTER variables for bounds evoked astounding stupidities, such as calculating the length of TEXT(L:L) by subtracting L from L!
Comparison runs of GNASH showed a saving of ~25-30% in its mass data scanning for this, involving all its two-dozen or so single-character comparisons, not just in LSTNB.

INTEGER*4 FUNCTION DAYNUM(YY,M,D) !Computes (JDayN - JDayShift), not JDayN.
C Conversion from a Gregorian calendar date to a Julian day number, JDayN.
C Valid for any Gregorian calendar date producing a Julian day number
C greater than zero, though remember that the Gregorian calendar
C was not used before y1582m10d15 and often, not after that either.
C thus in England (et al) when Wednesday 2'nd September 1752 (Julian style)
C was followed by Thursday the 14'th, occasioning the Eleven Day riots
C because creditors demanded a full month's payment instead of 19/30'ths.
C The zero of the Julian day number corresponds to the first of January
C 4713BC on the *Julian* calendar's naming scheme, as extended backwards
C with current usage into epochs when it did not exist: the proleptic Julian calendar.
c This function employs the naming scheme of the *Gregorian* calendar,
c and if extended backwards into epochs when it did not exist (thus the
c proleptic Gregorian calendar) it would compute a zero for y-4713m11d24 *if*
c it is supposed there was a year zero between 1BC and 1AD (as is convenient
c for modern mathematics and astronomers and their simple calculations), *but*
c 1BC immediately preceeds 1AD without any year zero in between (and is a leap year)
c thus the adjustment below so that the date is y-4714m11d24 or 4714BCm11d24,
c not that this name was in use at the time...
c Although the Julian calendar (introduced by himself in what we would call 45BC,
c which was what the Romans occasionally called 709AUC) was provoked by the
c "years of confusion" resulting from arbitrary application of the rules
c for the existing Roman calendar, other confusions remain unresolved,
c so precise dating remains uncertain despite apparently precise specifications
c (and much later, Dennis the Short chose wrongly for the birth of Christ)
c and the Roman practice of inclusive reckoning meant that every four years
c was interpreted as every third (by our exclusive reckoning) so that the
c leap years were not as we now interpret them. This was resolved by Augustus
c but exactly when (and what date name is assigned) and whose writings used
c which system at the time of writing is a matter of more confusion,
c and this has continued for centuries.
C Accordingly, although an algorithm may give a regular sequence of date names,
c that does not mean that those date names were used at the time even if the
c calendar existed then, because the interpretation of the algorithm varied.
c This in turn means that a date given as being on the Julian calendar
c prior to about 10AD is not as definite as it may appear and its alignment
c with the astronomical day number is uncertain even though the calculation
c is quite definite.
c
C Computationally, year 1 is preceded by year 0, in a smooth progression.
C But there was never a year zero despite what astronomers like to say,
C so the formula's year 0 corresponds to 1BC, year -1 to 2BC, and so on back.
C Thus y-4713 in this counting would be 4714BC on the Gregorian calendar,
C were it to have existed then which it didn't.
C To conform to the civil usage, the incoming YY, presumed a proper BC (negative)
C and AD (positive) year is converted into the computational counting sequence, Y,
C and used in the formula. If a YY = 0 is (improperly) offered, it will manifest
C as 1AD. Thus YY = -4714 will lead to calculations with Y = -4713.
C Thus, 1BC is a leap year on the proleptic Gregorian calendar.
C For their convenience, astronomers decreed that a day starts at noon, so that
C in Europe, observations through the night all have the same day number.
C The current Western civil calendar however has the day starting just after midnight
C and that day's number lasts until the following midnight.
C
C There is no constraint on the values of D, which is just added as it stands.
C This means that if D = 0, the daynumber will be that of the last day of the
C previous month. Likewise, M = 0 or M = 13 will wrap around so that Y,M + 1,0
C will give the last day of month M (whatever its length) as one day before
C the first day of the next month.
C
C Example: Y = 1970, M = 1, D = 1; JDAYN = 2440588, a Thursday but MOD(2440588,7) = 3.
C and with the adjustment JDAYSHIFT, DAYNUM = 25568; mod 7 = 4 and DAYNAME(4) = "Thursday".
C The Julian Day number 2440588.0 is for NOON that Thursday, 2440588.5 is twelve hours later.
C And Julian Day number 2440587.625 is for three a.m. Thursday.
C
C DAYNUM and MUNYAD are the infamous routines of H. F. Fliegel and T.C. van Flandern,
C presented in Communications of the ACM, Vol. 11, No. 10 (October, 1968).
Carefully typed in again by R.N.McLean (whom God preserve) December XXMMIIX.
C Though I remain puzzled as to why they used I,J,K for Y,M,D,
C given that the variables were named in the INTEGER statement anyway.
INTEGER*4 JDAYN !Without rebasing, this won't fit in INTEGER*2.
INTEGER YY,Y,M,MM,D !NB! Full year number, so 1970, not 70.
Caution: integer division in Fortran does not produce fractional results.
C The fractional part is discarded so that 4/3 gives 1 and -4/3 gives -1.
C Thus 4/3 might be Trunc(4/3) or 4 div 3 in other languages. Beware of negative numbers!
Y = YY !I can fiddle this copy without damaging the original's value.
IF (Y.LT.1) Y = Y + 1 !Thus YY = -2=2BC, -1=1BC, +1=1AD, ... becomes Y = -1, 0, 1, ...
MM = (M - 14)/12 !Calculate once. Note that this is integer division, truncating.
JDAYN = D - 32075 !This is the proper astronomer's Julian Day Number.
a + 1461*(Y + 4800 + MM)/4
b + 367*(M - 2 - MM*12)/12
c - 3*((Y + 4900 + MM)/100)/4
DAYNUM = JDAYN - JDAYSHIFT !Thus, *NOT* the actual *Julian* Day Number.
END FUNCTION DAYNUM !But one such that Mod(n,7) gives day names.
Could compute the day of the year somewhat as follows...

c + if Month > 2 then FebLength - 30 else 0;

END FUNCTION MUNYAD !A year has 365.2421988 days...
INTEGER FUNCTION PMOD(N,M) !Remainder, mod M; always positive even if N is negative.
c For date calculations, the MOD function is expected to yield positive remainders,
c in line with the idea that MOD(a,b) = MOD(a ± b,b) as is involved in shifting the zero
c of the daynumber count by a multiple of seven when considering the day of the week.
c For this reason, the zero day was chosen to be 31/12/1899, a Sunday, so that all
c day numbers would be positive. But, there was generation at Reefton in 1886.
c For some computers, the positive interpretation is implemented, for others, not.
c In the case MOD(N,M) = N - Truncate(N/M)*M, MOD(-6,7) = -6 even though MOD(1,7) = 1.

Overview
This task seems to conflate 3 different programming challenges
1. Transforming a nested, hierarchical structure of data into linear presentation structure (a stream of printable characters)
2. Acquiring/generating the calendar data that will be presented (specifically, support for arbitrary years and for non-Gregorian schemes)
3. Constraining the presentation according to some configuration information (e.g. terminal width and ASCII character codes).
Additionally, there seems to be some implicit desire for presentation decoration options (e.g. grid dividers, spacing between elements, addition of a banner) My strategy is to separate these various domains into separate families of functions that can be composed to solve the problem of actually generating a specific calendar.
1. Grid structure functions
The following functions were motivated by the recognition that a calendar is really a set of nested grid structures. The overall calendar is just a few elements arranged in a column, e.g. banner, year/title, and a grid of months. The grid of months is a rectangular arrangement of individual months that are all styled similarly but vary a bit in the data they contain. Each month is a grid of 3 elements in a column: the month name as title, a header row of the names of the weekdays, and a grid of integers representing the specific days/dates. Each day is a cell that could be considered an atomic element or could be considered a 1x1 matrix. The latter allows for cells to have all of the styling options of the higher level grid elements.
At each level, a grid is "regular" in the sense that its elements are constrained to columns and rows with nothing "spilling out" of those columns/rows. By nesting the grids in various ways, you can achieve "non-regular" patterns.
Mathematica has many wrappers for handling the presentation of such structured and nested data, including Grid, TextGrid, Row, Column, and Multicolumn. However, these are just wrappers that a Mathematica Notebook knows how to present in the UI. You could apply Normal or ToString to these wrappers to get a true textual representation, but the results are not easily predictable and are extremely sensitive to the options you have included in the wrappers. Since we are going to want fine level control over spacing, alignment, borders, etc, using these wrappers would be, unfortunately, not very helpful for providing a plain, textual output.
Therefore, I've chosen to implement "raw" textual grids from scratch with a function called DataGrid. There are two versions of DataGrid. The first version allows you to specify exactly the height and width of each row and column in terms of number of string characters. The second version allows you to specify just the "macro" grid dimensions, and the actual size of each cell will be determined by calculating the width among cells in the same column and max height among cells in the same row. With those max values, it calls the first GridData function. The cell dimensions do not account for spacing and borders, which are added after the cell is scaled to the correct character dimensions. A variety of decoration options can also be supplied. The effect of these will be demonstrated in the examples below. Each version acts on a list of cells that are already rectangular arrays of data (though their dimensions obviously don't already need to be identical--that's part of the job of DataGrid, and it's why DataGrid can be composed/nested). Also, the list of cells is "flat", and its length does not need to conform to an exact rectangle (again, this is a job of DataGrid).
DataGrid[
rowHeights:{__Integer},
colWidths:{__Integer},
spacings:{_Integer,_Integer},
borderWidths:{{_Integer,_Integer},{_Integer,_Integer}},
options_Association,
data:{__List?MatrixQ}]:=
With[
(*Need to make sure we have sensible defaults for the decoration options.*)
{alignment=Lookup[options,"alignment",{0,0}],
background=Lookup[options,"background"," "],
dividers=Lookup[options,"dividers",{" "," "," "}],
border=Lookup[options,"border"," "],
dims={Length[rowHeights],Length[colWidths]}},
(*Pad the data so that it will fit into the specified rectangle (list of lists).*)
With[{augmentedData=PadRight[data,Times@@dims,{{{background}}}]},
(*Create a matrix of dimensions based on desired rectangle. Once we have a matrix of cells we can "thread" these two matrices and use that data to coerce each cell into its final dimensions.*)
With[{cellDims=ArrayReshape[Outer[List,rowHeights,colWidths],{Times@@dims,2}]},
(*MatrixAlign, defined below, rescales and aligns each cell's data.*)
With[{undecoratedGrid=Partition[MapThread[MatrixAlign[alignment,#1,background][#2]&, {cellDims,augmentedData}],dims[[2]]]},
(*Add the spacing to each row.*)
With[{dividedRows=MapThread[Transpose[Riffle[#2,{ConstantArray[dividers[[2]],{#1,spacings[[2]]}]},{2,-2,2}]]&, {rowHeights,undecoratedGrid}]},
(*Add the spacing between rows.*)
With[{dividedColumn=Riffle[dividedRows,{Transpose[Riffle[ConstantArray[dividers[[1]],{spacings[[1]],#}]&/@colWidths,{ConstantArray[dividers[[3]],spacings]},{2,-2,2}]]},{2,-2,2}]},
(*Assemble all cell rows into actual character rows. We now have one large matrix.*)
With[{dividedGrid=Catenate[Map[Flatten,dividedColumn,{2}]]},
(*Add borders.*)
ArrayPad[dividedGrid,borderWidths,border]]]]]]]];
DataGrid[dims:{_Integer,_Integer},spacings_,borderWidths_,options_,data:{__List?MatrixQ}]:=
(*Calculate the max height for each row and max width for each column, and then just call the previous DataGrid function above.*)
With[
{rowHeights=Flatten@BlockMap[Max[Part[#,All,All,1]]&,ArrayReshape[Dimensions/@data,Append[dims,2],1],{1,dims[[2]]}],
colWidths=Flatten@BlockMap[Max[Part[#,All,All,2]]&,ArrayReshape[Dimensions/@data,Append[dims,2],1],{dims[[1]],1}]},
DataGrid[rowHeights,colWidths,spacings,borderWidths,options,data]];
(*This could probably be simplified, but I like having all of the aligment options explicit and separate for testability.*)
MatrixAlign[{-1,-1},dims_,pad_]:=PadRight[#,dims,pad]&;
MatrixAlign[{-1,0},dims_,pad_]:=PadRight[CenterArray[#,{Dimensions[#][[1]],dims[[2]]},pad],dims,pad]&;
MatrixAlign[{-1,1},dims_,pad_]:=PadRight[PadLeft[#,{Dimensions[#][[1]],dims[[2]]},pad],dims,pad]&;
MatrixAlign[{0,-1},dims_,pad_]:=CenterArray[PadRight[#,{Dimensions[#][[1]],dims[[2]]},pad],dims,pad]&;
MatrixAlign[{0,0},dims_,pad_]:=CenterArray[#,dims,pad]&;
MatrixAlign[{0,1},dims_,pad_]:=CenterArray[PadLeft[#,{Dimensions[#][[1]],dims[[2]]},pad],dims,pad]&;
MatrixAlign[{1,-1},dims_,pad_]:=PadLeft[PadRight[#,{Dimensions[#][[1]],dims[[2]]},pad],dims,pad]&;
MatrixAlign[{1,0},dims_,pad_]:=PadLeft[CenterArray[#,{Dimensions[#][[1]],dims[[2]]},pad],dims,pad]&;
MatrixAlign[{1,1},dims_,pad_]:=PadLeft[#,dims,pad]&;
(*While the grid functions make no assumptions about the format of the data, we will be using them with string/character data, and we will eventually want to output a calendar as a single large string. AsString gives us a standard method for transforming a matrix of characters into a string with rows delimited by newlines.*)
AsString[matrix_List?MatrixQ]:=StringRiffle[matrix,"\n",""];
To illustrate how DataGrid works, I'll create some sample data-grids and assemble them together into a larger data-grid, and then I'll use DataGrid itself to present all of these results. Notice the options for alignment, borders, spacings, etc.
DataA={{"A"}};
GridA = DataGrid[{2},{5},{0,0},{{1,1},{1,1}},<|"border"->"*","alignment"->{1,-1}|>,{DataA}];
DataB = {{"B"},{"B"}};
GridB =
DataGrid[{4,3},{4,8},{2,3},{{0,0},{0,0}},<|"background"->".","alignment"->{0,1},"dividers"->{"-","|","+"}|>,{DataB,DataB,DataB}];

HeaderGrid is a helper that defers the "gridding" of the individual header cells and data cells to functions that get passed in. There are some assumptions about presentation that feed into this design, but if your requirements differ, it's fairly easy to follow this same basic pattern of accepting functions that do the lower level work--you would just need to organize that work differently.
HeadedGrid[
finalSpacings:{_Integer,_Integer},
finalBorderWidths:{{_Integer,_Integer},{_Integer,_Integer}},
finalOptions_Association,
headerCellGridder_Function,
rawHeaders:{__String},
dataCellGridder_Function,
rawData:{__String}]:=
With[
{finalDims={Ceiling[(Length@rawData+Length@rawHeaders)/Length@rawHeaders],Length@rawHeaders},
headerCells=headerCellGridder/@List/@List/@Characters[rawHeaders],
dataCells=dataCellGridder/@List/@List/@Characters[rawData]},
DataGrid[finalDims,finalSpacings,finalBorderWidths,finalOptions,Join[headerCells,dataCells]]];
(*An example with a few decorations:*)
HeadedGrid[

MonthGrid will use HeadedGrid for the main part of the month, and it will take another gridding function to handle the title (month name). I could have simplified the method signature by having the caller pass in a HeadedGrid function directly, but I liked exposing more control with this function. MonthGrid offers the convenience of specifying a leading offset for the month (month and week boundaries don't typically align, so this allows for starting on the correct day of the week without requiring the caller to munge the data).
MonthGrid[
finalSpacings:{_Integer,_Integer},
finalBorderWidths:{{_Integer,_Integer},{_Integer,_Integer}},
finalOptions_Association,
titleGridder_Function,
monthName_String,
monthSpacings:{_Integer,_Integer},

{titleGridder[List/@List/@Characters[monthName]],
HeadedGrid[monthSpacings,monthBorderWidths,monthOptions,headerCellGridder,weekdayNames,dayCellGridder,ArrayPad[days,{dayOffset,0},""]]}];
(*A compact example:*)
MonthGrid[{0, 0}, {{0, 0}, {0, 0}}, <||>,
DataGrid[{1, Length@#}, {0, 1}, {{1, 1}, {0, 0}}, <||>,ToUpperCase@#] &,

DataGrid[{1}, {2}, {0, 0}, {{0, 0}, {0, 0}}, <|"alignment" -> {-1, 1}|>, #] &,

At this point we have everything we need to generate a calendar. Since ASCII art is just a matrix of characters, we could trivially handle the display of the Snoopy banner. To make things more interesting, let's instead just display a magnified version of the calendar year as a banner.
FractalChars takes a string and rasterizes each character and then replaces each black pixel with the original character. The output is a matrix of characters suitable as a datum in the argument to DataGrid.
FractalChars[rasterSize_,font_,char_String/;1==StringLength[char]]:=
ReplaceAll[ImageData[ImageCrop[Binarize[Rasterize[Style[char,FontFamily->font],RasterSize->rasterSize]]]],{1->" ",0->char}];
FractalChars[rasterSize_,font_,word_String]:=FractalChars[rasterSize,font,#]&/@Characters[word];

2. Calendar data functions
Fortunately, Mathematica has many powerful calendar-related functions. Unfortunately, the semantics of calendars is sufficiently complicated that there is no practical way to create just a few standard data generators that will cover all of the implied cases. For example, the seemingly simple concept of "first day of the year" is ambiguous. The Jewish year uses one start day for religious holidays and another day for civil/secular purposes. The task definition referenced the switch-over from the Julian calendar to the Gregorian calendar, but this did not happen simultaneously around the globe, and many regions adopted the Gregorian calendar surprisingly recently. Assigning a number to a year is not standardized across calendars (e.g. consider the Chinese and Jewish calendars). The Cotsworth Calendar (effectively the International Fixed Calendar) has days that aren't assigned to any month or week--they're just dangling special days. So, we can provide some simple, general helper functions, but we assume that the calendar maker will be responsible for dealing with special cases.
(*Mathematica makes it easy to get month names and day names for several standard calendars.*)
MonthNames[]:=MonthNames["Gregorian"];
MonthNames[calType_]:=Lookup[CalendarData[calType,"PropertyAssociation"],"MonthNames"];
WeekdayNames[]:=WeekdayNames["Gregorian"];
WeekdayNames[calType_]:=Lookup[CalendarData[calType,"PropertyAssociation"],"DayNames"];
(*Since month boundaries don't align with week boundaries on most calendars, we need to pad month data with empty cells. I was tempted to create a function that would generate offsets for a given year on a given calendar, but even that required too many decisions on the part of the calendar maker to be feasible. So, I removed all of the calendar semantics. If you provide the fixed small group length (week length), the initial offset, and the list of the large group lengths (month lengths), this function will give you the offsets you need for each large group (month).*)
Offsets[groupLength_,firstOffset_,lengths_List]:=FoldPairList[{#1,Mod[#1+#2,groupLength]}&,firstOffset,lengths];
For the year 1969 on the Gregorian calendar, Mathematica can give us all of the data we need.
Data1969=GroupBy[Most[DateRange[DateObject[{1969,1,1}],DateObject[{1+1969,1,1}]]],DateValue[#,"MonthName"]&];
InitialOffset1969=QuantityMagnitude[DateDifference[PreviousDate[DateObject[{1969,1,1}],Sunday],DateObject[{1969,1,1}]]];

It's a bit more involved to create the data for a calendar that displays the switch from Julian to Gregorian. A few major European Catholic countries made the switch in 1582, so I'll generate data for that scenario. The switch happened in October, with Thursday Oct 4 being followed by Friday Oct 15. Mathematica provides tools to both fetch the calendar data and then fiddle with the structures so that I can highlight the relevant month and dates.

3. Output configuration
The only remaining task is to automate the fitting of calendar data to a specified width. We could approach this in the most general way, which would allow us to fit an arbitrary data set into any pre-specified rectangle. This approach would need to actually iterate over the possible dimensions for the large scale grid, creating the grid each time and computing its dimensions. It would stop when it found dimensions that fit (for some definition of "fit"). Alternatively, if we pick a specific set of formatting options such that each month has a standard size, it's a simple matter of arithmetic to determine a grid that fits. I'm going to implement something closer to the more general approach, but only concerned with widths, and only doing the grid generation in an abstract way.
WidestFitDimensions will output data about the best fit it found, including the dimensions (which could be used in DataGrid) and the width of the best fit grid. There is no guarantee that a strict fit can be found, so it also provides the actual width of the best fit, and the user can determine what to do with the results. One could create another helper gridding function that uses WidestFitDimensions to automatically generate the grid, but I've already demonstrated such helper functions, so I'll just focus on computing the grid dimensions here.
WidestFitDimensions[
targetWidth_Integer,
columnSpacings_Integer,
leftRightBorderWidths:{_Integer,_Integer},
data:{__List?MatrixQ}]:=
With[
{widths=Last/@Dimensions/@data,
fullWidthOfRow=Total[ArrayPad[Riffle[#,columnSpacings],leftRightBorderWidths,1]]&},
With[
{fullWidthOfGrid=Max[fullWidthOfRow/@#]&},
With[
{isTooLarge=(targetWidth<fullWidthOfGrid[#])&},
With[
{bestFitGrid=
NestWhile[Partition[widths,-1+Last@Dimensions@#,-1+Last@Dimensions@#,{1,1},0]&,
{widths},isTooLarge[#]&,1,-1+Length@widths]},
<|"dimensions"->Dimensions@bestFitGrid,"width"->fullWidthOfGrid@bestFitGrid|>]]]];
Checking best fit for our 1969 calendar for a few widths.
(*Choose a best fit for our 1969 calendar data on 80 character wide display.*)
WidestFitDimensions[80,4,{0,0},MonthGrids1969]
- Output:
<|dimensions->{4,3},width->68|>
(*Choose a best fit for our 1969 calendar data on 132 character wide display.*)
WidestFitDimensions[132,4,{0,0},MonthGrids1969]
- Output:
<|dimensions->{3,5},width->116|>
(*Can we fit into a 20-character wide display?*)
WidestFitDimensions[20,4,{0,0},MonthGrids1969]
- Output:
<|dimensions->{12,1},width->20|>
