{{Lua|Module:Age}}

This template returns the number of weeks that have elapsed between two dates. If the second set of parameters is not included it will automatically calculate the days between a given date and today.

== Usage ==
Each date can be entered in a single parameter, or each date can be entered as three parameters: year, month, day.

* <code><nowiki>{{age in weeks|month1=6|day1=14|year1=1946|month2=8|day2=19|year2=1946}}</nowiki></code> → {{age in weeks|month1=6|day1=14|year1=1946|month2=8|day2=19|year2=1946}}
* <code><nowiki>{{age in weeks|1946|6|14|1946|8|19}}</nowiki></code> → {{age in weeks|1946|6|14|1946|8|19}}
* <code><nowiki>{{age in weeks|1946-6-14|1946-8-19}}</nowiki></code> → {{age in weeks|1946-6-14|1946-8-19}}
* <code><nowiki>{{age in weeks|14 June 1946|Aug 19, 1946}}</nowiki></code> → {{age in weeks|14 June 1946|Aug 19, 1946}}
* <code><nowiki>{{age in weeks|month1=11|day1=07|year1=2012}}</nowiki></code> → {{age in weeks|month1=11|day1=07|year1=2012}}
* <code><nowiki>{{age in weeks|7 November 2012}}</nowiki></code> → {{age in weeks|7 November 2012}}

An error is shown if an entered date is not valid (1900 was not a leap year).<!--fixed wikitext to avoid tracking category-->
* <code><nowiki>{{age in weeks|31 January 1899|29 February 1900}}</nowiki></code> → <strong class="error">Error: Second date should be year, month, day</strong>
