Template:Date serial
This template returns the date serial in year for a date specified by month number and day of month. By default the year is considered non leap, but this may be overridden.
- Syntax:
- {{Date serial|month number|day of month}}
- {{Date serial|month number|day of month|year}}
- {{Date serial|month number|day of month|leapyear=is leap}}
- The year parameter is optional, if specified, the named leapyear parameter is ignored.
- The named leapyear parameter (optional, default value 0, unless year is specified) is non-zero to get the proper date serial on dates starting at March 1st on leap years.
