In many East Asian cultures—including Chinese, Korean, Vietnamese, and others—age is not just a number tied to your birth date on the Gregorian calendar. Instead, the lunar age system is a deeply cultural and symbolic way of counting one’s age based on the lunar calendar. If you’ve ever wondered why someone from East Asia says they’re a year or two older than their “actual” age, the answer lies in this unique system.
In this comprehensive guide, we’ll explore the concept of lunar age, show you how to calculate it using our Lunar Age Calculator tool, and answer all the common questions about lunar aging traditions.
Lunar Age Calculator
🧠 What Is Lunar Age?
Lunar age is calculated based on the East Asian lunar calendar, where:
- A person is considered 1 year old at birth.
- A person’s age increases by one every Lunar New Year, not on their actual birthday.
This means that two people born a day apart in the same Gregorian year may have different lunar ages depending on when the Lunar New Year falls.
📱 How the Lunar Age Calculator Works
Our Lunar Age Calculator simplifies this traditionally complex calculation with a single click. Based on your Gregorian date of birth, it:
- Determines your birth year.
- Compares it with the current year.
- Adds 1 to simulate the fact you’re already considered 1 at birth.
- Adjusts depending on whether your birthday has occurred before or after the Lunar New Year (approximated as February 4).
The calculator is accurate, quick, and does not require any understanding of lunar calendars.

🧪 Example
Let’s walk through a quick example:
- Gregorian Date of Birth: June 15, 1995
- Today’s Date: January 20, 2025
- Lunar New Year Estimate: February 4, 2025
Since the birthday has not yet occurred this year and the Lunar New Year hasn’t arrived, the lunar age is calculated as:
2025 - 1995 = 30
Lunar New Year not passed yet → Age = 30
Birthday not passed yet → Age = 30
Add 1 for birth year = 31
Your Lunar Age: 31 years
