Birth Date Calculator

This is a handy tool developed by Ben Buckner to help calculate birth dates from the death date and age at the time of death. Many old tombstones and death records list only these two facts and leave it to us to figure out the birth date. This does it with a simple keystroke or two. You must fill in all blanks for the "age" row. If you do not know the months or days, simply enter 0.
