* Age at Death Calculator *
Code written by Frederick R. Griswold, May, 2004

This utility makes four different calculations related to the age at death. To choose the calculation you want to run, make sure that the appropriate radio button below is filled by clicking on the button.
 
The first calculation accurately determines the date of birth using the death date, and the age at death. However, many tombstone makers calculated the age at death by assuming 30-day months. If this seems to be the case with the inscription you are working with, then try the second method. The other two calculations are self explanatory.

Calculate the birthdate using the age at death and the date of death
      (Though this is the more accurate method, it was not always used.)

Calculate the birthdate using the age at death and the date of death
      (Though this assumes 30-day months, it is used on many inscriptions.)
