Age is a simple number in most countries you’re born at zero, and you add a year on your birthday. But in China and Korea, traditional systems count age differently, leading to fascinating cultural variations. In this guide, we’ll explore Chinese Age vs Korean Age, how each is calculated, why they differ, and how you can instantly find yours using our free calculators.
What Is Chinese Age?
The Chinese Age system is based on the lunar calendar and traditional beliefs. Here’s how it works:
- You are considered 1 year old at birth (counting the time in the womb).
- Everyone’s age increases together on Chinese New Year, not on their birthday.
- The calendar follows moon cycles, so Chinese New Year usually falls between late January and mid-February.
Example: If you were born in August 2000 and today is March 2025 (after Chinese New Year), your Chinese Age would be:
- International Age: 24
- Add 1 year at birth = 25
- Add 1 year after Chinese New Year = 26 years old

What Is Korean Age?
The Korean Age system is similar in some ways but has its own twist:
- You are 1 year old at birth.
- Your age increases by 1 year every January 1st, regardless of your birthday.
- This means your Korean Age can be 1–2 years older than your international age.
Example: If you were born in August 2000 and today is March 2025:
- International Age: 24
- Add 1 year at birth = 25
- Add 1 year on January 1st = 26 years old
