Chinese lunar calendar converter: confirm the year and leap month first
The same lunar month name maps to different Gregorian dates in different years, and leap months cannot be omitted. Date conversion is a calendar lookup, not a personal reading; its first job is to preserve an accurate input.
The short answer
A lunar date needs its year and leap-month status. Keep both the original input and converted Gregorian result so that birth-chart calculation does not lose information.
Required conversion fields
- Year, month and day
- Whether the input is Gregorian or lunar
- Whether the lunar month is a leap month
- Location and time zone for cases near midnight
Why leap months exist
Lunar months follow phases of the Moon while seasons and solar terms follow the Sun. Some years add a leap month to coordinate the two, so a lunar month without its year and leap status may be ambiguous.

Frequently asked questions
Does the same lunar birthday fall on the same Gregorian date each year?
No. The correspondence changes each year and must be looked up for that specific year.
Can I ignore a leap month?
No. A leap month and the ordinary month with the same number are different months and convert to different dates.
