How This Age Calculator Works

Calculating age manually is surprisingly tricky. A year isn’t always 365 days (leap years add complexity), and months vary from 28 to 31 days. Our age calculator uses precise date arithmetic to give you an exact result — no approximations.

Real-World Example

Scenario: Born on 15 February 2000, today is 10 May 2025.

Calculation:

• Years: 2025 – 2000 = 25 years
• Months: May (5) – February (2) = 3 months
• Days: 10 – 15 = -5 → borrow 1 month (April has 30 days) → 30 – 15 + 10 = 25 days
• Final Age: 25 years, 2 months, 25 days

Our tool does this in milliseconds — no math required!

Frequently Asked Questions (FAQ)

❓ Is this age calculator really free?
Yes! Our age calculator is 100% free, with no hidden costs, subscriptions, or ads. We believe essential tools should be accessible to everyone.
❓ Is my birth date stored or sent to a server?

Yes! The tool supports dates from January 1, 1900, onward. For dates before 1900, results may vary due to calendar reforms (e.g., Julian to Gregorian transition).
❓ How does it handle leap years?
Our algorithm accounts for leap years (e.g., 2000, 2004, 2024) and adjusts February’s length automatically, ensuring precise day counts.
❓ Can I use this for official documents?
While our calculator is highly accurate, always verify critical results with official records (e.g., birth certificates). For legal purposes, consult relevant authorities.
