Lunar Age Calculator
Calculate your age in Chinese lunar and Hijri calendars with Chinese New Year and pregnancy-year adjustments.
What Is Lunar Age?
Lunar calendars track time using moon cycles instead of the solar year used by the Gregorian calendar. Many cultures still use lunar systems for holidays, traditions, and age customs. This calculator converts your everyday Gregorian age into Chinese lunar age or Hijri lunar age.
Chinese Lunar Age
In the Chinese tradition, a person is considered one year old at birth because pregnancy counts as the first year of life. An additional year is added after Chinese New Year, not on your birthday. That means your Chinese lunar age is usually one or two years higher than your international age.
If Chinese New Year has passed: Lunar age = Gregorian age + 2
If Chinese New Year has not passed: Lunar age = Gregorian age + 1
Hijri Lunar Age
The Hijri calendar is about 10 days shorter than the Gregorian year. Over time, that difference adds up. A common approximation adds 2.7% to your current age:
Hijri age = (Gregorian age × 0.027) + Gregorian age

Frequently Asked Questions
Why is my Chinese age higher than my real age?
Chinese age includes the time spent in the womb as one year and adds another year after Chinese New Year. These customs differ from Western age counting, which starts at zero at birth and increases on your birthday.
I'm 28. How old am I in the Chinese calendar?
If Chinese New Year has already passed, you are 30 in the Chinese lunar system. If it has not passed yet, you are 29.
Is Hijri age the same as my Islamic calendar birth year?
Not exactly. This tool gives a quick age estimate based on the shorter Hijri year. For formal religious or legal dates, use an official Hijri date converter tied to your exact birth date.
Does Chinese New Year fall on the same date every year?
No. Chinese New Year moves between late January and mid February because it follows the lunar calendar. Always confirm whether the holiday has passed for the current year.
