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 and no ads — 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.
