Age Calculator
Leave blank for today
An age calculator computes your exact age in years, months, and days from your birth date to today (or another target date). Useful for official documents, medical records, eligibility verification, and birthday countdowns.
💡
Pro Tip
For official purposes (passport, contracts, benefits), age is measured in completed years — you are 35 until your 36th birthday, not the day you turn 35. Check the specific rule if precision matters.

Did You Know?
Different cultures define age differently. In South Korea, the traditional system adds 1 year at birth (counting the time in the womb) and adds another year on New Year's Day, not your birthday. South Korea officially switched to the international standard in 2023.
