How it works

- The tool computes the difference in calendar years, months and days, accounting for month lengths and leap years.
- It also shows total days lived and the countdown to your next birthday.
Frequently asked questions
How is age calculated?
By subtracting the birth date from today, carrying over months and days so you get an exact years/months/days breakdown rather than a rounded number.
Does it account for leap years?
Yes — the calculation uses real calendar dates, so leap years and varying month lengths are handled correctly.
