Age Calculator
Pick your date of birth to see your exact calendar age, your totals in weeks, days, hours and minutes, and how long until your next birthday.
How to read your result
The headline figure counts complete calendar units: full years first, then full months since your last birthday, then the remaining days. The unit cards below it restate the same span as running totals. Hours and minutes are the complete calendar-day span multiplied into smaller units; they do not use an exact birth time.
Month lengths and leap days come from the real calendar, so a birthday on the 31st or on 29 February is handled without rounding.
