Is Tomb-Sweeping Day a lunar calendar or a Gregorian calendar?

Tomb-Sweeping Day is calculated according to the Gregorian calendar, because Tomb-Sweeping Day is one of the 24 solar terms, and all solar terms are calculated according to the Gregorian calendar.

Qingming is one of the 24 solar terms in China, which are divided according to the position of the sun on the ecliptic. The sun starts from the vernal equinox, and every advance 15 degrees is a solar term, and Tomb-Sweeping Day is at 15 degrees on the ecliptic. Because the 24 solar terms objectively reflect the changes of temperature, rainfall and phenology throughout the year, ancient working people used them to arrange agricultural activities.

"Huainanzi Astronomical Training" says: On the fifteenth day after the vernal equinox, it was sunny and windy when the fingers crossed. According to "100 questions at the age of 10", everything grows clean and clear at this time, so it is called clear and bright. The temperature rises and the rainfall increases, which is a good season for spring ploughing and planting. Therefore, before and after Qingming, it is necessary to order melons, beans and trees to avoid Qingming agricultural proverbs.
