Is Qingming Festival a traditional festival in China? The origin of the Qingming Festival is ultra-clear.

It's fixed.

Most of them are on April 5th, but they can also be on April 4th.

Qingming Festival is one of the important "Eight Festivals of the Year" in China, which is generally around April 5 of the Gregorian calendar.

Qingming Festival, also known as the Qingqing Festival, is at the turn of mid-spring and late spring, that is, the 108th day after the winter solstice.

Qingming, one of the 24 solar terms. Many people think that Qingming is on April 5, but in fact, Qingming is changed between April 4 and 6, for example, this year's Qingming is April 4. So, why is Qingming always around April 5th?

Because the Qingming Festival is derived from the Qingming Festival in the 24 solar terms of the Chinese lunar calendar, it is different from the Gregorian calendar date that everyone often uses.

The date of the Qingming Festival is different every year, this is because the Qingming Festival we celebrate is the lunar calendar, and everyone generally accepts the solar calendar, so there is a conflict between the two legislations.

Because the Qingming Festival is calculated according to the lunar calendar. The lunar calendar is not a lunar calendar but a luni-solar calendar, taking the cycle of moon phase change, i.e., the synodic month as the length of the month, referring to the solar return year as the length of the year, and setting the 24 solar terms and leap months to adapt the average calendar year to the return year.

Because the Qingming Festival is calculated according to the lunar calendar, and we use the Gregorian calendar to count the time in our daily life, the date of the Qingming Festival is different every year.

The lunar calendar is not the same as the Gregorian calendar, and the lunar calendar passes slowly, so the date of the Qingming Festival on the Gregorian calendar is different every year.

The date of the Qingming Festival is not calculated according to the time, but according to the solar yellow longitude. Zhang Mingying explained that the earth revolves around the sun for about 365 days, and the earth's orbital route is called the ecliptic. The ecliptic longitude is the longitude metric coordinates on the ecliptic.

According to astronomical conventions, the ecliptic longitude of the sun is measured from west to east from the vernal equinox, and is divided into 360 degrees. The ancients divided the 360 degrees of the sun's ecliptic longitude into 24 equal parts, each with 15 degrees, which is 1 solar term. The number of days between the two solar terms is about 15 days, and there are 24 solar terms throughout the year.

During the Qingming solar term, the earth's revolution reaches the 15-degree position of the sun's ecliptic longitude. However, since the time for the earth to orbit around is not necessarily a strict 365 days, there may be irregular dates in the division of solar terms. Under normal circumstances, Qingming is about 15 days after the vernal equinox every year, and the specific date does not change by more than 3 days.
