In this entry, the functions for converting Gregorian dates to dates
in the Mayan calendar take the form of zero-arity filters that expect,
as input, strings of the form "yyyy-mm-dd" or JSON Date objects of the
form {"year", "month", "day"}.
<syntaxhighlight lang="jq">
### General utilities
def lpad($len): tostring | ($len - length) as $l | (" " * $l) + .;
def rpad($len): tostring | ($len - length) as $l | . + (" " * $l);
# days_between("2020-01-01"; "2020-01-02") #=> 1
# days_between("2020-01-02"; "2020-01-01") #=> -1
def days_between($yyyymmddBefore; $yyyymmddAfter):
(yyyymmddBefore | strptime("%Y-%m-%d") | mktime) as $before
| (yyyymmddAfter | strptime("%Y-%m-%d") | mktime) as $after
# leap seconds are always inserted
| (($after - $before) / (24*60*60) | floor) ;
### `Date` objects
def Date($year; $month; $day): {$year, $month, $day};
# Convert a Date object to a string yyyy-mm-dd
# Other inputs are (currently) unscathed.
def yyyymmdd:
if type == "object" then "\(.year)-\(.month)-\(.day)"
