A regular month and a leap month can share a number
A leap month exists only for a particular month in a particular year. A nonexistent leap month or lunar day is rejected. Korean lunar dates can differ from Chinese lunar dates.
Supported conversion-table interval
The solar interval is 1000-02-13 through 2050-12-31; the lunar interval is 1000-01-01 through 2050-11-18. Gregorian-reform gap dates are validated. Cycle names are calendar references, not public-holiday determinations.
Common questions
Why is a date rejected with leap month enabled?
That year may not have a leap month with the selected number. Uncheck leap month for a regular date and check the lunar month’s final day.
