Template:Age in weeks/doc

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.



An error is shown if an entered date is not valid (1900 was not a leap year).
 * → Error: Second date should be year, month, day
