In South Korea, a different age system is traditionally used:
- Everyone is 1 year old at birth
- Everyone ages 1 year on January 1st (not on their birthday)
- This means Koreans can be 1-2 years "older" than their international age

Frequently Asked Questions
How is age calculated?
Age is calculated by finding the difference between your birth date and the current date. Our calculator provides the result in years, months, and days for precision.

Yes! Our calculator automatically accounts for leap years, ensuring accurate age calculation even for people born on February 29th.
What if I was born on February 29th?
If you were born on a leap day (February 29th), the calculator will still work correctly. In non-leap years, your birthday is typically celebrated on February 28th or March 1st.

Is the age calculation accurate?
Yes, our calculator uses precise date arithmetic to provide accurate age calculations down to the day.
Can I calculate age from a future date?
While the calculator is designed for birth dates in the past, you can use it to calculate how old someone will be on a future date by entering that date as the "current" date.
