模板:Age in weeks/sandbox
 | 這是Template:Age in weeks（差異）的沙盒。 參見本模板的測試樣例。 |
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.
{{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}}→ 624{{age in weeks|7 November 2012}}→ 624
An error is shown if an entered date is not valid (1900 was not a leap year).
{{age in weeks|31 January 1899|29 February 1900}}→ Error: Second date should be year, month, day
