Line 1:
This module provides date functions for use by other modules. Dates in the [[Wikipedia:Gregorian calendar|Gregorian calendar]] and the [[Wikipedia:Julian calendar|Julian calendar]] are supported, from 9999 BCE to 9999 CE. The calendars are proleptic—they are assumed to apply at all times with no irregularities.
A date, with an optional time, can be specified in a variety of formats, and can be converted for display using a variety of formats, for example, 1 April 2016 or April 1, 2016. The properties of a date include its [[Wikipedia:Julian day|Julian date]] and its Gregorian serial date, as well as the day-of-week and day-of-year.
Dates can be compared (for example, <code>date1 <= date2</code>), and can be used with add or subtract (for example, <code>date + '3 months'</code>). The difference between two dates can be determined with <code>date1 - date2</code>. These operations work with both Gregorian and Julian calendar dates, but <code>date1 - date2</code> is nil if the two dates use different calendars.
