Frequently asked questions
- How precise is the age calculation?
- Down to whole days: years, months, and days, plus totals in days, weeks, months, and hours. Dates are handled as calendar dates, so leap years are counted but times of day are not.
- Can I calculate age at a specific date?
- Yes. Set the "as of" date to anything - past, present, or future - to see age at that moment.
- Does it handle time zones?
- The calculation uses your browser's local time zone. For precise cross-timezone calculations, enter birth and target dates in the same zone.
- Is my birth date stored?
- No. All calculation happens in your browser. No data is sent to any server or saved across sessions.
- What does it show besides the age?
- Total days, weeks, months, and hours lived, the number of days until the next birthday, the weekday you were born on, and the matching zodiac sign.
- How are partial months counted?
- When the target day of the month falls before your birth day, the calculator borrows the length of the preceding month, so the result reads the way people normally count, as a number of whole months plus leftover days.
