வார்ப்புரு:Birth based on age as of date

This template calculates the birth year and current age based on the age as of a date. This is useful when a reference states only their age at the time of the reference's publication.

 {{birth based on age as of date |age |year|month|day}} 

The age, year, and day must be supplied as இயல் எண்s; month can be specified as a natural number as well as by name or abbreviation (e.g. "August" or "Aug"). The கிரெகொரியின் நாட்காட்டி is assumed, with no special support provided for dual dating or the difference between Old Style and New Style dates.

If they are not known, the "day" and "month" fields can be omitted; this is useful if, for example, only the publication year for a source is known.

To suppress the age field:

 {{birth based on age as of date |age |year|month|day |noage=1}} 

With the "noage=1" option, the month and day can be "1".

To replace the '/' separator with ' or ' in compliance with WP:APPROXDATE, add |mos=1

{{birth based on age as of date|50 |2024|06|9|mos=1}}

1973 or 1974 (அகவை 51)

If, for example, a reference dated July 4, 2024 mentions that someone is 50 years old, that person's birth year and age can be rendered using:

{{birth based on age as of date |50 |2024|July|4}}
