Frequently asked questions
- How is age calculated?
- By counting whole calendar years, then remaining whole months, then the leftover days — the same way ages are counted in everyday life.
- What about people born on 29 February?
- In non-leap years the next birthday is treated as 1 March.
- Is my date of birth stored?
- No. It stays in your browser and is never sent anywhere.
