Lunar Calendar
Calculates the Lunar Calendar based on the current year and month.
Input in the Japanese calendar system is available starting from January 1, Meiji 6 (1873), following the adoption of the Gregorian calendar.
Input for dates before the Common Era is not supported.
The practice of listing the lunar calendar alongside the Gregorian calendar was abolished in 1910, and no official lunar calendar is currently published.
This library performs calculations based on celestial mechanics, so the results may differ from officially designated past dates.
The lunar calendar data for 1870–2072 has been verified for consistency with *Shin Koyomi Benricho* and *Rekijitsu Taikan*.
For 1947, an intercalary second month is used. (“New Calendar Handbook” uses an intercalary second month, while “Compendium of Calendar Days” uses an intercalary third month.)
