This tool calculates the exact time between a birth date and any target date (defaulting to today), broken down into years, months and days — plus the total number of days lived.
How to use this tool
- Enter your date of birth.
- Optionally change the "as of" date.
- Click Calculate Age to see the result instantly.
Why use our age calculator?
It accounts for leap years and varying month lengths, so the years/months/days breakdown is precise, not a rough estimate.
