Frequently Asked Questions

How is the age calculated exactly?+

The difference between the birth date and today is decomposed into full years, then remaining months, then days — the same method used for official documents.

Are leap years handled correctly?+

Yes — the calculation uses real calendar arithmetic, so February 29 birthdays and leap-year spans come out right.

When do I need an exact age?+

Visa and passport applications, school enrollment cutoffs, insurance forms, retirement calculations — anywhere "age in years, months and days" is required.

Can I calculate age at a past or future date?+

The tool computes age as of today. For a different reference date, the day difference display helps you adjust quickly.
