This tool calculates an exact age between any two dates. Enter a date of birth and the date you want to measure to, and it returns the age in years, months, and days, along with total days and weeks lived and a countdown to the next birthday.

Frequently asked questions

How is age calculated?
The calculator finds the difference between the date of birth and the chosen date, accounting for varying month lengths and leap years, and expresses it in years, months, and days.
Can I calculate age at a past or future date?
Yes. Set the 'age at date' to any date on or after the date of birth to find the age at that point.
