The solar calendar corresponds to the lunar calendar. Who invented the lunar calendar?
At present, China is still using a calendar parallel to the Gregorian calendar. People used to call it the "lunar calendar", but it is actually a kind of lunar calendar, that is, the summer calendar, which is not the real "lunar calendar".
Normal year 12 months, 30 days in the big month, 29 days in the small month, and 354 or 355 days in the whole year (which month is big and which month is small in a year, which varies from year to year). Because the number of days in each year is about eleven days worse than that in the solar year, there are seven leap months in nineteen years, and there are 383 or 384 days in a year with leap months. According to the position of the sun, a solar year is divided into 24 solar terms to facilitate agricultural planting and other activities. The chronology is matched with heavenly stems and earthly branches, with a period of 60 years. According to legend, this calendar originated in the Xia Dynasty, so it is also called the Xia calendar. Also known as the old calendar.
People often call the summer calendar "lunar calendar" because the 24 solar terms are of great significance to agricultural production, but they are determined according to the position of the sun on the ecliptic and belong to the solar calendar. Therefore, it is not appropriate to call the summer calendar the lunar calendar.
