About Us

mychronologicalagecalc.com is a free, simple tool for working out exact chronological age in years, months and days.

We built it for the people who calculate ages every working day: speech-language pathologists, school psychologists, therapists and teachers scoring standardized tests. It supports both common borrowing methods, optional rounding, and shows the full working so you can double-check every result.

Everything runs in your browser. We never see or store the dates you enter.
