{{Shortcut|template:gsd}}

== 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. By default this template gives the serial for today. To find the serial for another date fill in the date into this code: '''<syntaxhighlight lang="wikitext">{{Gregorian serial date|month = |day = |year = }}</syntaxhighlight>'''

'''Today's date is {{Gregorian serial date}}.'''
