Examples: Use week day names as preferred by Template:Weekday in month

New page

{{Documentation subpage}}

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.

: <kbd><nowiki>{{</nowiki>Date serial<nowiki>|</nowiki></kbd>''month number''<kbd><nowiki>|</nowiki></kbd>''day of month''<kbd><nowiki>}}</nowiki></kbd>

* 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.

== Examples ==
* <code><nowiki>{{date serial|{{CURRENTMONTH}}|{{CURRENTDAY}}|leapyear={{isLeapYear}}}}</nowiki></code> → {{date serial|{{CURRENTMONTH}}|{{CURRENTDAY}}|leapyear={{isLeapYear}}}}
* <code><nowiki>{{date serial|1|1}}</nowiki></code> → {{date serial|1|1}}
* <code><nowiki>{{date serial|1|1|2000}}</nowiki></code> → {{date serial|1|1|2000}}
* <code><nowiki>{{date serial|1|1|leapyear=1}}</nowiki></code> → {{date serial|1|1|leapyear=1}}
* <code><nowiki>{{date serial|2|28}}</nowiki></code> → {{date serial|2|28}}
* <code><nowiki>{{date serial|3|1}}</nowiki></code> → {{date serial|3|1}}
* <code><nowiki>{{date serial|3|1|leapyear=0}}</nowiki></code> → {{date serial|3|1|leapyear=0}}
* <code><nowiki>{{date serial|3|1|1999}}</nowiki></code> → {{date serial|3|1|1999}}
* <code><nowiki>{{date serial|3|1|leapyear=1}}</nowiki></code> → {{date serial|3|1|leapyear=1}}
* <code><nowiki>{{date serial|3|1|2000}}</nowiki></code> → {{date serial|3|1|2000}}
* <code><nowiki>{{date serial|3|26}}</nowiki></code> → {{date serial|3|26}}
* <code><nowiki>{{date serial|5|1}}</nowiki></code> → {{date serial|5|1}}
* <code><nowiki>{{date serial|12|31}}</nowiki></code> → {{date serial|12|31}}
* <code><nowiki>{{date serial|12|31|leapyear=1}}</nowiki></code> → {{date serial|12|31|leapyear=1}}
* <code><nowiki>{{date serial|12|31|1999}}</nowiki></code> → {{date serial|12|31|1999}}
* <code><nowiki>{{date serial|12|31|2000}}</nowiki></code> → {{date serial|12|31|2000}}

Days since September 1st:
* <code><nowiki>{{#expr: {{date serial|{{CURRENTMONTH}}|{{CURRENTDAY}}}} - {{date serial|9|1}} }}</nowiki></code> → {{#expr: {{date serial|{{CURRENTMONTH}}|{{CURRENTDAY}}}} - {{date serial|9|1}} }}

First Sunday in November is November {{Weekday in month|{{CURRENTYEAR}}|11|Sunday|1}}, {{CURRENTYEAR}}
* <code><nowiki>{{date serial|11|{{Weekday in month|{{CURRENTYEAR}}|11|Sunday|1}} }}</nowiki></code> → {{date serial|11|{{Weekday in month|{{CURRENTYEAR}}|11|Sunday|1}} }}
