739714

Template documentation[view] [edit] [history] [purge]

Usage

This template gives the serial day according to the proleptic Gregorian calendar, hence with the leap year exceptions of the 100 and 400 year rule, and with backward extrapolation, including year 0 and negative years, with Monday, 1 Jan 1 being day 1. This template handles . By default this template gives the serial for today. To find the serial for another date fill in the date into this code: {{Gregorian serial date|month = |day = |year = }}

Today's date is 739714.

Examples

  • {{gsd|year=-401|month=1|day=1}} gives -146826_ERROR - Can not handle dates before January 1, 1 A.D.
  • {{gsd|year=-401|month=12|day=31}} gives -146462_ERROR - Can not handle dates before January 1, 1 A.D.
  • {{gsd|year=-400|month=1|day=1}} gives -146461_ERROR - Can not handle dates before January 1, 1 A.D.
  • {{gsd|year=-400|month=12|day=31}} gives -146096_ERROR - Can not handle dates before January 1, 1 A.D.
  • {{gsd|year=-1|month=1|day=1}} gives -729_ERROR - Can not handle dates before January 1, 1 A.D.
  • {{gsd|year=-1|month=12|day=31}} gives -365_ERROR - Can not handle dates before January 1, 1 A.D.
  • {{gsd|year=0|month=1|day=1}} gives -364_ERROR - Can not handle dates before January 1, 1 A.D.
  • {{gsd|year=0|month=12|day=31}} gives 1_ERROR - Can not handle dates before January 1, 1 A.D.
  • {{gsd|year=1|month=1|day=1}} gives 1
  • {{gsd|year=1|month=12|day=31}} gives 1
  • {{gsd|year=2000|month=12|day=31}} gives 730485 (5 times the number of days of a cycle, 146,097)
  • {{gsd|year=1985|month=1|day=1}} gives 724642
  • {{gsd|year=1985|month=4|day=12}} gives 724743
  • {{gsd|year=1981|month=8|day=12}} gives 723404
  • {{gsd|year=1953|month=10|day=2}} gives 713228
