Frequently asked questions
Is this age calculator free?
Yes, and there is no limit on how many times you can use it.
Can I calculate age as of a future or past date, not just today?
Yes. Change the "Age as of" field to any date.
Why does it show years, months and days instead of just total days?
Because that's how people usually state an age (e.g. "34 years, 2 months, 10 days"). The total day count is also shown for reference.
Is my birth date sent to a server?
No. Calculation happens locally in your browser.
