About us

agecompute.com is a small, independent age calculator built to answer one question well: exactly how old you are — or someone else is — right now, down to the second. No accounts, no ads, and no data collection. Just date math done properly, in your browser.

Most age calculators stop at "years old." This one goes further: precise years/months/days breakdowns, running totals in weeks, hours, minutes and seconds, upcoming milestone dates, a corrected age option for premature babies, and a few cultural extras like Korean age and Western and Chinese zodiac signs — built because they're genuinely useful, not just because they were easy to add.

Every calculation happens client-side, using plain JavaScript, the moment you type. Nothing about your date of birth is ever transmitted, logged, or stored anywhere. See our privacy policy for the full details.
