Leap June refers to the additional sixth month in the lunar calendar. There are usually 12 months in a lunar calendar year, but since the average length of lunar calendar months is about 29.5 days, a year only has about 354 days, which is about 11 days less than the 365 days in the solar calendar. In order to make up for this gap, the lunar calendar will adjust the time by adding leap months to ensure that the seasons of the lunar calendar are consistent with the solar calendar.

The setting of leap months follows the rule of "seven leap months in nineteen years", that is, there will be seven leap months in 19 years. Leap June is one of them. It occurs relatively infrequently, only about once every 19 years.
