Question

Regarding the origin of the winter month, according to the lunar calendar, the winter solstice must appear in the eleventh month of the lunar calendar. If there is an error, a leap month will be used to adjust it. If there is no leap month in a year, November of the lunar calendar is the eleventh month of the year. And because November of the lunar calendar is the month of the winter solstice among the 24 solar terms, November of the lunar calendar is also called It is the winter moon.

Answer 1

Yes, the above assumption is correct. The winter month, also known as 冬月 (dōng yuè), is the eleventh month of the lunar calendar.

So, It is the month of the winter solstice, the shortest day of the year in the Northern Hemisphere. This makes sense because the lunar calendar is based on the cycles of the moon, which has an average period of 29.5 days.

The winter solstice occurs about every 365.24 days, which is slightly longer than the lunar cycle. To keep the lunar calendar in sync with the solar year, an extra month, called a leap month, is added occasionally.
