Claus Toendering’s Frequently Asked Questions about calendars was a very useful resource. The implementation of Julian Day, Modified Julian Day, and Year Day comes from his FAQ. Markus Kuhn has a useful description of the ISO Standard 8601 for Date/Time notation. The W3 Consortium also has a useful Note.

Mike Sperber, Marc Feely, Dave Mason, and “Prfnoff” all made useful comments on previous versions of this draft. Thanks to Shriram Krishnamurthi for his editing help.

The date->string procedure uses a format string, based on GNU C’s date() procedure, as well as Scsh’s format-date procedure.
