Lunar Age Calculator

Lunar age, also known as Chinese lunar age, is a traditional way of calculating age based on the Chinese lunar calendar. Unlike the Gregorian calendar, where a person’s age increases on their birthday, the Chinese lunar age considers a newborn baby to be one year old at birth, and age increases on the Chinese New Year rather than the actual birth date.

If you’ve ever wondered, "What is my lunar age?" or "How do I find out my lunar age?", our advanced Lunar Age Calculator provides an accurate and user-friendly solution. With just a simple input of your birthdate, you can instantly determine your Chinese lunar age and understand the unique calculation behind it.

How Lunar Age is Calculated

The calculation of lunar age follows these simple steps:

1. A baby is considered 1 year old at birth in the Chinese system.
2. The age increases by one year on each Chinese New Year, not on the individual's actual birthday.
3. Depending on whether your birthday falls before or after the Chinese New Year in a given year, your lunar age may be one or two years more than your actual age.

Here’s the formula for calculating lunar age:

Lunar Age = (Current Lunar Year - Birth Lunar Year) + 1

For example, if you were born on March 15, 1995, your lunar birth year would be 1995, but if you were born on January 10, 1995, before the Chinese New Year, your lunar birth year would be 1994.

Let’s say the current year is 2024:

• If your lunar birth year is 1995, your lunar age is (2024 - 1995) + 1 = 30 years old.
• If your lunar birth year is 1994, your lunar age is (2024 - 1994) + 1 = 31 years old.
