Frequently Asked Questions
- How is age calculated?
- It counts complete years, then remaining months, then remaining days between your birth date and the target date (today by default).
- Can I calculate age at a past or future date?
- Yes. Set the optional "Age at date" field to any date. Leave it blank to calculate age as of today.
- Does it account for leap years?
- Yes. The total-days count uses real calendar dates, so leap years are handled correctly.
- Is my data sent anywhere?
- No. All calculations run in your browser.
