Chinese Age Calculator

Have you ever wondered why some people say they are one or two years older in Chinese tradition? This is because of the Chinese lunar age. It is different from the age we use in most countries, which is called the Western age.

In Chinese culture, your age is counted differently. It is used for many things, like the Chinese gender chart to guess a baby’s gender, or the zodiac calendar to understand personality and fortune.

How to Calculate Your Chinese Lunar Age ?

In Chinese tradition, a baby is already 1 year old at birth. Then, everyone adds a year on the Chinese New Year, not on their birthday.

Here is the simple formula:

Lunar Age = Current Lunar Year – Birth Lunar Year + 1

Let’s say your birth lunar year is 2010 and the current lunar year is 2025:

2025 – 2010 + 1 = 16 (Your Chinese lunar age is 16)

Chinese New Year Adjustment:

If you were born before the Chinese New Year in your birth year, count that year. If born after, use the previous lunar year.

East Asian Age Reckoning Traditions.

This method of counting age is called “sui” or East Asian age reckoning.

• Sui means years.

• Nominal age is the number used in tradition.

• Real age is what we use in modern life.

This system is used in countries like:

• China

• Korea

• Taiwan

• Vietnam

Each country has small differences, but the idea is the same: you are 1 year old at birth, and everyone gets older on New Year.

Many people ask: “Is the Chinese gender chart real?” or “Is lunar age always one year more?”

Here’s what we know:

• It is a cultural belief, not science.

• It has been used for hundreds of years.

Always talk to a doctor if you want to know your baby’s gender for sure.
