Find your exact age from your date of birth — in years, months, and days. Also see the total number of days you have lived and a countdown to your next birthday.
Full years are counted first, then the remaining months, then the remaining days.
Leap years are handled correctly, including birthdays on 29 February.
Months have different lengths, so day counting uses the real length of the month, not a fixed 30 days.
Age: Difference between date of birth and today
Next birthday: Days until the next anniversary of the birth date
How is age calculated for someone born on 29 February?
In years that are not leap years, the birthday is treated as 1 March for counting. This way, the age still goes up by one every year.
Why doesn't my age in months equal my age in years times 12?
Because months are not all the same length. This calculator counts real calendar months, instead of treating every month as equal.
