Calculate Exact Age From Date of Birth
An age calculator finds the time between a date of birth and another date. Use it to calculate current age, age on a future date, age on a past date, total days lived, total weeks, and days until the next birthday.
This calculator uses calendar dates, so month lengths and leap years are handled automatically. For leap day birthdays, the next birthday falls on the closest valid date in non-leap years.
