Template:Birth based on age at death: Difference between revisions

Template documentation

This is a customized wrapper for the {{Birth based on age as of date}} template, which means it's built upon the other template's code. Parameters from {{Birth based on age as of date}} will only work here if they have been added to this template. If you have questions, ask at the talk page!

This template calculates a person's approximate birth year based on their age at death. This is useful when a reliable source states only their age at death. This can also be used when a person is dead and a reliable source states only their age at the time of publication, but their actual death date is not known.
