Date of Birth Calculator

Many older tombstones only list the date of death and how old the person was in years/months/days. Instead of having to go through the hassle of getting out paper, pencil, calendar and trying to figure out which years were leap years, you can just enter the information into the calculator below and let the calculator do all the work for you.

**Please make entries in each box on lines 1 and 2 Use a zero where you do not have a number to enter. Then press the "Calculate" button.**
