Frequently Asked Questions
How is age calculated?
The calculator counts the full years, then the remaining months, then the remaining days between your date of birth and the comparison date, the same way you would say your age out loud.
Can I find my age on a past or future date?
Yes. Change the comparison date to any day and the calculator shows how old you were, or will be, on that date.
Does it handle leap years?
Yes. It uses real calendar dates, so leap years and different month lengths are counted correctly.
How long until my next birthday?
The result shows the date of your next birthday and the number of days remaining from the comparison date.
Is my information sent anywhere?
No. Everything runs in your browser. Your dates never leave your computer and it works offline once loaded.
Why are the total months and days different from my age?
Your age in years, months and days breaks the time into calendar parts, while the totals express the whole span in one unit, such as all the days added together.
