Age Calculator

Select your Date of birth

Today's date

Our Age Calculator computes your exact age from your date of birth to the current date — or any target date you specify. You'll see your age broken down into years, months, days, hours, and even minutes. Beyond just your age, the tool also shows your next birthday countdown, what day of the week you were born, and how many days until your next birthday.

Whether you need your precise age for a medical form, an official document, a visa application, or simply out of curiosity, our calculator gives you an accurate answer accounting for leap years, months of different lengths, and time zones.

Frequently Asked Questions

Does the calculator account for leap years?

Yes. The calculator accounts for leap years (years divisible by 4, except century years not divisible by 400) when calculating exact days.

Can I calculate age in months for a baby?

Yes. Enter the baby's date of birth and the current date, and the calculator will show the age in complete months and remaining days — the standard way pediatricians track infant development.

What if someone was born on February 29 (leap day)?

For people born on February 29, the calculator uses February 28 as their birthday in non-leap years — the most common legal convention.

Can I calculate someone's age on a future date?

Yes. Set the target date to any future date to calculate how old someone will be at that point. Useful for planning milestone birthday celebrations or retirement projections.
