The lunar calendar is not a simple lunar calendar, but a combination of yin and yang. Take the change period of the moon phase as the length of the month, add the "24 solar terms" component of the trunk calendar, and refer to the length of the tropical year of the sun as the year. By setting leap months, the average calendar year can adapt to the tropic year.

Therefore, strictly speaking, the lunar calendar in China should not be called the lunar calendar, but the combined calendar of yin and yang. Its years are divided into normal years and leap years. An average year is twelve months; A leap year is thirteen months.
