About this age calculator
Enter a date of birth and get an exact age: years, months and days, plus the totals in weeks, hours and minutes, and a countdown to the next birthday.
What people use it for
- Filling in a form that wants an exact age.
- Working out a child's age in months.
- Checking an age on a date in the future or the past.
- Finding which weekday someone was born on.
- Counting down to the next birthday.
How are months counted?
The way people say them: from the birth day to the same day number in a later month. Where that day does not exist — the 31st in a 30-day month — the count rolls to the end of that month.
Does it handle leap years?
Yes. Someone born on 29 February has their age counted on 28 February in ordinary years.
Can I get an age on a past or future date?
Change the second date from today to any other, and the age is worked out as of that day.
