How to use

Frequently asked questions
Is the age calculator free?
Yes, it is completely free with no sign-up, no limits and no software to install.
How does it calculate exact age?
It compares your birth date to the target date and counts the full years, then the remaining months and days, while accounting for leap years and the different number of days in each month.
Can I calculate age on a future or past date?
Yes. Set any target date instead of today and the calculator shows the age as of that exact day, whether it is in the past or the future.
What does total days lived mean?
It is the complete number of calendar days between the birth date and the target date, useful for spotting round-number milestones.
Does it count the day of birth?
Age starts at zero on the day of birth, so a full year is only completed on each birthday; the total days figure counts every day that has passed since.
Is my birth date kept private?
Yes. The calculation runs entirely in your browser and your dates are never sent to a server.
