Chrona: Age Calculator

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.
