Discordian date: Difference between revisions

This program is written to run under CP/M, and it takes a Gregorian date as an argument on the command line, in <code>DDMMYYYY</code> format.

Algol W doesn't have the array initialisation equivalent of MAD's VECTOR VALUES and also does not allow implicit declarations.

Algol W does not have I/O formsts or variable length strings in output, which makes this version somewhat longer.

This version is loosely based on a modified translation of the original ddate.c and like the original the leap year functionality is Julian not Gregorian.

disc 2012 2 29

see [[Talk:Discordian_date|talk page]]. But, in essence, this version uses season ordinals with a single imaginary day after the 59th of the first season, on leap years. This is implemented so that that imaginary day has been passed for all remaining days of a leap year.
