FAQ
Why does my age differ from another calculator?
Some calculators use simple day-count methods. This calculator uses real calendar months and leap years.
Can I calculate age on a future date?
Yes. Choose a future “as of” date, and the calculator will show your age on that date.
Does this work for leap-year birthdays?
Yes. If you were born on Feb 29, the next birthday will be calculated correctly depending on the calendar year.
