Find your exact age in years, months, days & more
This free age calculator finds your exact age in years, months and days from your date of birth. It also shows your age in total months, days, hours and minutes, the weekday you were born, your zodiac sign and a countdown to your next birthday.
You can calculate your age as of today or as of any other date, which is handy for forms, applications and planning.

If the chosen day of the month is earlier than the birth day, the calculator borrows days from the previous month. It also checks that the date exists, so a date such as February 31 is rejected.
The calculator subtracts your date of birth from the date you choose, in whole years first, then months, then days. If the day of the month is smaller than your birth day, it borrows days from the previous month, the same way you would do it by hand.

They are rough estimates for fun. Heartbeats assume about 70 beats per minute, nights slept equals the number of days, and meals assume three per day.
It uses the usual date ranges for each sign. The exact start and end dates can move by a day in different years, so people born on the edge of a sign may see a different sign elsewhere.
