Notes on using Rata Die dates with other tools.

MySQL

MySQL supports ordinal dates with a different epoch from Rata Die. To convert a Rata Die N to a MySQL date, use from_days(N+365). To convert a MySQL date D to a Rata Die, use to_days(D)-365.

Python

Python has direct support for Rata Die dates, calling them "proleptic Gregorian ordinals". To convert a Rata Die N to a Python date object, use datetime.date.fromordinal(N). To convert a Python date object D to a Rata Die, use D.toordinal().
