FAQ
How exact is this calculator?
It counts real calendar days, including leap years, so totals are exact for the dates you enter.
Can I calculate age on a future date?
Yes — set the “age at” date to any future date, for example a school or job application deadline.
Is my birth date stored?
No. The calculation happens in your browser and nothing is saved.
