**mpfeil**How would you calculate age based off a birth date?

- JotForm Support
**Mike**Thank you for contacting us.

We can use the following formula to calculate the age.

floor ( (CurrentDate - BirthDate) / 365.242 )

Please see the next animation.

In this case we assume that year is by average 365.242 days to consider the leap years. The formula is not 100% correct, but it should work in most of the cases.

If you need any further assistance, please let us know.
