How it works
Enter your date of birth and, optionally, a different reference date. The tool subtracts the two calendar dates and breaks the difference down into full years, remaining months, and remaining days — accounting for leap years automatically.
Frequently asked questions
How is my exact age calculated?
We take the difference between your birth date and today (or a date you choose), then break it down into full years, remaining months, and remaining days.
Does it account for leap years?
Yes. The calculation uses real calendar dates, so leap years are handled automatically and never throw off the result.
Can I calculate my age on a future or past date?
Yes. Change the "Calculate age as of" field to any date to see your age at that point in time.
