Module:Age (sandbox)

This template returns the number of months, weeks and days that have elapsed between two dates.

Usage

{{Age in years, months, weeks and days |month1 = |day1 = |year1 = |month2 = |day2 = | year2 = }}

Note that all parameters default to the current date, so for example, the second set of parameters can be left out to calculate elapsed time since a past date:

{{Age in years, months, weeks and days |month1 = 1 |day1 = 1 |year1 = 1 }} → 2023 years, 7 months, 1 week and 4 days

Or simply, using the simpler parameter names, compatible with {{Age in years, months and days}}:

{{Age in years, months, weeks and days |month = 1 |day = 1 |year = 1 }} → 2023 years, 7 months, 1 week and 4 days

Alternatively, the first set of parameters can be left out to get the time left until a future date, such as the next Wikipedia Day:

{{Age in years, months, weeks and days |month2 = 1 |day2 = 15 |year2 = 2025 }} → 5 months and 3 days
