模板:Age in weeks
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
[编辑]Each date can be entered in a single parameter, or each date can be entered as three parameters: year, month, day.
{{age in weeks|month1=6|day1=14|year1=1946|month2=8|day2=19|year2=1946}}→ 9{{age in weeks|1946|6|14|1946|8|19}}→ 9{{age in weeks|1946-6-14|1946-8-19}}→ 9{{age in weeks|14 June 1946|Aug 19, 1946}}→ 9{{age in weeks|month1=11|day1=07|year1=2012}}→ 629{{age in weeks|7 November 2012}}→ 629
An error is shown if an entered date is not valid (1900 was not a leap year).
