Frequently Asked

How accurate is the age calculation?

Our calculator accounts for leap years, varying month lengths (28-31 days), and exact time differences. It is mathematically precise for personal and educational use.

Does it work for leap year birthdays (Feb 29)?

Absolutely! If you were born on February 29, we calculate your age correctly, treating non-leap years appropriately for birthday countdowns.

Is my data stored anywhere?

No. All calculations happen entirely in your browser. Your birth date never leaves your device — we have no server, no database, and no tracking.

What are the “fun facts” based on?

Fun facts use scientific averages: ~100,000 heartbeats/day, ~8 hours sleep/day, and ~12 full moons/year. They are estimates for entertainment.
