In the distant future (such as 2104) and some past years (specific historical data needs to be consulted), there may also be a leap May. These years are determined according to the leap month rules of the lunar calendar. Due to the complex astronomical calculations involved in the conversion between the lunar calendar and the Gregorian calendar, we usually refer to the already prepared lunar calendar to confirm the specific leap month year.
The above information is for reference only. If you need more information about leap months, it is recommended to consult the lunar calendar or consult astronomical experts.
