Compute Birth Date
If you press F2 on the Edit screen, you will get a pop-up window where you can enter the death date of a person and the age at death. It will then compute the birth date. This is useful if you see a tombstone with the age at death.
Note: You may need to be in a non-grid field when you press F2. For example click on the name field for a person and then press F2 to bring up the date calculator.
Type the death date using the date format you have picked in Options, or else just enter numbers and press Tab to convert the date.
Type the number of years, months, and days and it will compute the birth date. Then if you want you can pick Copy to Clipboard and then go to a date field and Paste in the date.
Note: The computed birth date will be wrong if the information is invalid. For example, if you say a person died on March 31 and was born 1 month before, then it will say February 31 which is invalid. There is no valid date exactly 1 month before March 31.
