FAQs

Q: Does this calculator work for past dates (e.g., historical figures)?

A: Yes! It accurately computes age for any past date, even from centuries ago.

Q: Why does it not allow future birthdates?

A: Age calculation requires a birthdate in the past. Future dates would give negative results, which don’t make sense.

Q: How does it handle leap years?

A: The JavaScript Date object automatically accounts for leap years, ensuring February 29th births are calculated correctly.

Q: Does it store or send my birthdate anywhere?

A: No! All calculations happen locally in your browser—no data is sent to any server.
