Age-Finder is a free collection of age and date calculators. Enter a date of birth and get an exact answer: your age in years, months and days, the days until your next birthday, the gap between two people, your zodiac sign and more.
What we build
Each calculator answers one question well. The tool sits at the top of its page, and a guide below it explains the method with worked examples, so you can check any result by hand.
How we work
- Exact, consistent rules. Every calculator follows the same calendar rules, described in our methodology.
- Private by design. Calculations run in your browser. The dates you enter are never sent to us or stored.
- Sourced guides. Where a page relies on rules or data from official bodies, such as retirement ages or life tables, it names its sources.
- Free, with no account. No sign-up and no download, on any phone or computer.
