Age Calculator
Find your exact age in years, months, and days. Calculate the time between two dates or find out how many days until your next birthday.
How Age is Calculated
Age is typically determined by the number of years since birth. However, there are different methods depending on cultural context. This calculator uses the most common Western method, which treats birthdays as the transition point for reaching a new year of age.
Did you know?
In some cultures, a person is considered one year old at birth, and their age increases on the Lunar New Year rather than their actual birthday.
Leap Years
If you were born on February 29th, your legal birthday in non-leap years is usually determined by local law as either February 28th or March 1st.
