Age Calculator questions.
How does this age calculator handle months?
It uses real calendar months, so months with 28, 29, 30, or 31 days are handled based on the actual dates entered.
Can I calculate age on a past or future date?
Yes. Change the age-on date to calculate age on any valid date after the date of birth.
