About this app

Chrona is the fastest, cleanest way to work out exactly how old someone is — to the day. No ads, no accounts, no sign-up, and it works completely offline. Open the app and you're already there: pick a date of birth and Chrona instantly shows the exact age in years, months and days, plus the total days, weeks, hours and minutes, the weekday it fell on, and a countdown to the next birthday. Need the age as of a specific date — like a test date or a deadline? Flip on "as of a date" and Chrona gives you a precise chronological age (years; months; days), the format used in standardized assessments. INCLUDED • Exact age from any date of birth • Age as of any specific date • Total days, weeks, hours and minutes • Day of the week born + next-birthday countdown CHRONA PRO — one-time unlock, no subscription • Difference mode: the exact span between any two dates • Saved people: keep everyone's age live, sorted by whose birthday is next • Share & export any result in a tap Private by design. Everything stays on your device — Chrona never collects your data and never needs the internet. Terms of Use (EULA): https://obelisk.club/agecalculator/terms
