What's the difference between the lunar calendar and the solar calendar? Which is better and more accurate?

Lunar calendar, one of the traditional calendars in China, is also called lunar calendar, lunar calendar, ancient calendar, yellow calendar, summer calendar and old calendar. The lunar calendar is a combination of the lunar calendar and the lunar calendar. On the one hand, the moon revolves around the earth as a "moon", and the average length of the moon is equal to "the first moon", which is the same as the lunar calendar principle, so it is also called the "lunar calendar"; On the other hand, the "leap month" is set to make the average length of each year as close as possible to the tropic year, and the 24 solar terms are set to reflect the characteristics of seasonal changes, so the lunar calendar combines the characteristics of the yin-yang calendar, also known as the "yin-yang calendar". Up to now, almost all people in China and countries such as Korean Peninsula and Viet Nam still use the lunar calendar to calculate traditional festivals such as Spring Festival, Mid-Autumn Festival and Dragon Boat Festival.

Solar calendar, also known as solar calendar. A calendar is based on the period of the earth around the sun. Its average calendar year is a tropic year, and there are two calendar years, one is a normal year, and the other is a leap year, and the leap year is only one day away from the normal year. Generally speaking, the Gregorian calendar is an international Gregorian calendar (i.e. "solar calendar"). Because there are 365.2422 days in a year, not only 365 days, there is a leap year every four years, that is, the 29th day is added in February. After a leap of four years, it has been revised to 365.25, but there is still an error, so one leap year will be reduced every hundred years, namely 1700, 1800 and 65438+. It was revised to 365.24. Finally, a leap year is added every 400 years, that is, 1600, 2000 and 2400 all have leap years. Finally, it was revised to 365.2425, with an error of 0.0003. It takes about 3000 years for a day's error to appear, so it has always been very accurate.

solar calendar

Gregorian calendar (Gregorian calendar) is a common calendar in most countries in the world, which was revised from "julian calendar". Julian calendar is the calendar decided by Julius Caesar, commander-in-chief of ancient Rome, in 46 BC.

The solar calendar is a calendar based on the movement of the earth around the sun. It takes the earth's orbit around the sun as a year. The length of the tropical year is 365.2422 days, which means 365 days, 5 hours, 48 minutes and 46 seconds. The cumulative four years is 23 hours 15 minutes and 4 seconds, which is about equal to one day. Therefore, every four years, 1 day is increased, and 366 days are obtained at the end of February. This is a leap year. However, four years plus 1 day actually adds 44 minutes and 56 seconds to the return year. When the product reaches 128, one more day will be counted, that is, three more days will be counted in 400 years.
