If I have the age of a person in one cell how do i get their date of birth in
the next cell? Is there a formula?
 
Assuming you know their birthday this year (in cell A1) and their age this
year (in cell B1), one way is:

=IF(A1>=TODAY(),DATE(YEAR(A1)-B1,MONTH(A1),DAY(A1)),DATE(YEAR(A1)-B1-1,MONTH(A1),DAY(A1)))

Regards
