How many days are there in the Lunar New Year? How long is the Gregorian calendar year?

There are 354.3672 days without leap month in the lunar calendar, 383.8978 days with leap month and 365.425 days in the Gregorian calendar.

Lunar calendar is a combination of yin and yang based on lunar calendar (summer calendar) and solar calendar. 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 solar tropical year 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.

The AD, that is, the Gregorian calendar era, is a kind of chronology that originated from 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. In A.D. 1582, the then Pope Gregory XIII approved the promulgation of this law.

Extended data:

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 of tropic year are more than 12 moons and shorter than 13 moons.
