The difference between solar calendar and lunar calendar

Lunar calendar is a traditional calendar in China, and it also has names such as lunar calendar, summer calendar, Han calendar and Han calendar. But in fact, it is not a lunar calendar, but a "yin-yang calendar", which is based on the movement cycle of the moon around the earth.

The Gregorian calendar is the Gregorian calendar and the Gregorian calendar, which is based on the movement cycle of the earth around the sun. Now it is a universal calendar.

Second, the difference between days.

The lunar calendar is based on the cycle of the moon's movement around the earth. It takes 29.5306 days for the moon to circle the earth, so the lunar calendar has only 29 or 30 days each month, and there will be no 3 1 day. Then use solar terms to regulate yin and yang to form the Lunar New Year.

The Gregorian calendar is based on the period of the earth's revolution around the sun. It takes 365.2422 days for the earth to go around the sun, which is called the tropic year. Therefore, a year on the Gregorian calendar is 365 days. If four years are accumulated, there will be one more day, so there will be one more day in February of each leap year, and there will be 366 days in the whole year. Other months are generally 30 days or 3 1 day.

Third, the difference between successive.

Generally speaking, the lunar calendar is slower than the Gregorian calendar. For example, the Gregorian calendar is July 30, 20 19, and the lunar calendar on this day is June 28.

Fourth, the difference between festivals.

The lunar calendar is an ancient calendar, so traditional festivals in China adopt the lunar calendar, such as the Spring Festival, Lantern Festival, Dragon Boat Festival and Double Ninth Festival.

The solar calendar is a newly adopted world calendar, so the festivals it calculates are usually emerging festivals, such as Arbor Day, Women's Day, Labor Day, Teacher's Day and so on.
