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.
