Template:Age/doc

This template returns the number of full years between two specified dates. If the second set of parameters is not included, it will return the number of full years between a specified date and today's date.

Syntax:

{{age|year1|month1|day1|year2|month2|day2}} or

{{age|year1|month1|day1}}

Examples:

{{age|1989|7|23|2003|7|14}} returns "13"

{{age|1989|7|23}} returns "35"

When using this template to calculate a person's age at death or a person's age on a specified date (rather than the person's current age), please substitute it into the page.

Example: {{subst:age|1989|7|23|2003|7|14}}

Note:

This template does not check for incorrect input:

{{age|1980|7|14|1993|6|233}} returns "12" (surplus days do not count as extra months)

{{age|1980|7|14|1993|88|14}} returns "13" (surplus months do not count as extra years)

Use with caution on in-universe pages

Please note that this template, and really everything in category:age calculation templates should be 'used with caution on in-universe pages. They all assume that there is no year zero, which our in-universe rule on years does not. This is because there are several in-universe sources, not the least of which is the 1996 movie and its novelisation, which assume that there is a year zero. For ease of calculation, our in-universe time calculation templates, like {{timeline}}, are therefore based on a different principle than this one — namely, that year 0 does exist.

In practice, this means absolutely nothing to the calculation time of between two dates, so long as you're trying to figure out the distance between any two dates after 1/1/1 AD.
