FAQ
How do I find my Chinese birthday?
Enter your Gregorian birth date in year, month, and day order. The calculator converts that date to the Chinese lunar month and day and finds its next Gregorian occurrence. This differs from calculating your full-year age.
What happens if I was born in a leap lunar month?
The result identifies leap-month birthdays. When the target year has no matching leap month, this calculator uses the regular month and explains the fallback. If day 30 does not exist in that month, it uses the last day. Family celebration customs may differ.
What does this lunar birthday calculator show?
It converts a Gregorian birth date into a Chinese lunar date, then shows the lunar month, lunar day, Ganzhi year, zodiac reference, next lunar birthday, and nominal lunar age reference.
Does it include personal judgment?
No. The calculator only explains calendar information. It does not provide personal judgment or prediction results.
How is nominal lunar age calculated?
It uses the traditional lunar-year formula: current lunar year minus birth lunar year plus one. It is only a cultural reference, not a legal or medical age.
Why can a lunar birthday fall on different Gregorian dates?
The Chinese lunar calendar and Gregorian calendar are different systems, so the same lunar month and day usually map to different Gregorian dates each year.
