Frequently Asked Questions
Why does manual age calculation sometimes come out wrong?
Simple year subtraction doesn't account for whether the birthday has occurred yet this year, which causes common off-by-one errors.
Can I calculate age as of a past or future date?
Yes — change the 'As of Date' field to any date you want.
