How many days are there in the lunar calendar year? How long is the Gregorian calendar year?
The lunar calendar is based on the lunar calendar (summer calendar) and the solar calendar, combining yin and yang. Taking the change period of the moon phase as the length of the month, plus the "24 solar terms" component of the dry calendar, and referring to the length of the tropical year of the sun as the year, the average calendar year is adapted to the tropical year by setting leap months. Therefore, the lunar calendar has both lunar and solar elements.
AD, the Gregorian calendar era, is a chronological method that originated in western society. Julian calendar was originally called the Christian era, also known as the Gregorian calendar or A.D., and was reformed by Italian doctor and philosopher aloysius Lilius. 1582, the then Pope Gregory XIII approved its promulgation.
Extended data:
The length of the calendar month in the lunar calendar is subject to the first month of the lunar calendar, with 30 days in the first month and 29 days in the second month. The first lunar month and the second lunar month complement each other, making the average length of calendar months close to the first lunar month. The length of the lunar calendar year is based on the tropic year, but the days in a tropic year are more than 12 moons and shorter than 13 moons.
The year after the outbreak of the Revolution of 1911 (19 12), the then government of the Republic of China adopted the Gregorian calendar as its national calendar. In chronology, the chronology of the AD is parallel to that of the Republic of China.
1949 On September 27th, the first plenary session of China People's Political Consultative Conference passed that the newly established People's Republic of China (PRC) adopted the Gregorian calendar and the Gregorian calendar year commonly used by most countries in the international community.
