Age Calculator
How old are you — exactly in years, months and days, plus total days, the weekday you were born, and your next birthday.
Frequently asked questions
How is exact age calculated?
We count the complete years since your date of birth, then the remaining complete months, then the days — exactly how age is worked out on documents. Varying month lengths and leap years are accounted for.
How does this differ from the date calculator?
This gives your age (years/months/days) and next birthday from one birth date. The date calculator adds/subtracts days and finds the difference between any two dates.
Can I find my age at a past or future date?
Yes. Leave the "age at date" field empty for today, or pick a date to see your age as of that exact day.
Is my data stored?
No. Everything is computed in your browser — your date of birth is never sent or saved.
