Frequently Asked Questions

How is age calculated exactly?

Age is calculated by finding the difference between two dates. The year difference gives base age; if the current month/day hasn't reached the birth month/day yet, one year is subtracted. The remaining months and days are then computed from the difference.

Can I calculate age between two past dates?

Yes. Many age calculators allow you to set a custom 'as of' date instead of today, letting you find how old someone was at any specific point in history.

Is this calculator free?

Yes. All tools on zenicalculator.com are completely free to use with no registration required.
