What's the difference between lunar calendar and lunar calendar?

The differences between the lunar calendar and the lunar calendar are as follows:

First of all, their origins are different. The Gregorian calendar is equal to the solar calendar, which is a universal date and our usual date. The lunar calendar is equal to the lunar calendar, which is the date used for farming in ancient China, that is, the date indicated by the small print below the calendar.

Secondly, the two algorithms are different. The solar calendar is a calendar in which the earth revolves around the sun for one year, and the lunar calendar is a calendar in which the moon revolves around the earth for one month and 12 months is a year (13 months in leap years).

the lunar calendar is calculated by taking the full moon as a month, which lasts for 12 hours, 44 minutes and 2.8 seconds on the 29th, and the full moon as a year, which lasts for 354 days, 8 hours, 48 minutes and 33.6 seconds. Of the 12 months in each year, 6 odd-numbered months (that is, January, March, May, July, September and November) are big buildings with 3 days per month, and 6 even-numbered months (February, April, June, August, October and December) are small buildings with 29 days per month. In leap years, December is changed to big month.

the lunar calendar is the current modern calendar in China, which belongs to the combined calendar of yin and yang, that is, the combined calendar of lunar calendar and solar calendar. According to the changing cycle of the lunar phase, each lunar phase changes to one month, taking the tropic of the sun as the length of one year, and adding 24 solar terms and setting leap months to adapt the average calendar year to the tropic year. The integration of lunar calendar and solar calendar in the lunar calendar forms a method of combining yin and yang, which was called Xia calendar in ancient times because of the use of Xia Zheng.

The lunar calendar is a new calendar used after 197. Its years are divided into flat years and leap years, with a flat year of 12 months and a leap year of 13 months. Months are divided into big months and small months, with a big month of 3 days and a small month of 29 days. The average calendar month is equal to a full moon. The lunar calendar is based on the cycle of the moon's ebb and flow. A new moon is a month, about 29.53 days, and the whole year is generally 354 or 355 days, which is 11 days less than the 365 or 366 days in the Gregorian calendar year (also known as the tropic year and the solar year).
