How to Figure a Birthdate

How To Figure a Birthdate

Remember this number:   8870

This is the number to remember when you want to find the birthdate of someone when you only have the date of death and their age!  How do you figure the birthdate?

Suppose the person died May 6, 1889........ (18890506), at the age of 71 years, 7 months, 9 days.........(710709)


Write the year, month, day as:



Subtract the age at death



This gives the figure:



Now subtract the #8870



The result is:


Year: 1817; 9th month (Sept); 27th day = 27 Sept. 1817
