was established as early as the spring and Autumn Period in China. It has a history of more than 2500 years, and has always been a festival and solar term that has attracted much attention.

So how to calculate the date of the winter solstice? Is it according to the Gregorian calendar or the lunar calendar? Let the old yellow calendar introduce it to you.
Q: is the winter solstice according to the Gregorian calendar or the lunar calendar? A: the winter solstice is calculated according to the Gregorian calendar. The 24 solar termsand
are determined in combination with the movement cycle of the sun and are divided according to the position of the sun on the ecliptic (that is, the earth's orbit around the sun), so the date of each solar term is subject to the Gregorian calendar. Depending on the sun starting from the vernal equinox (zero degrees of the Yellow meridian, at this moment the sun shines vertically on the equator), every 15 degrees forward is a solar term; Running for a week and back to the spring equinox, it is a year of return, which is 360 degrees. When the sun reaches 270 ° of the Yellow meridian, it is the winter solstice. The date ofand
solar terms is relatively fixed in the Gregorian calendar. For example, the date of the winter solstice is always between December 21 and 23 of the Gregorian calendar. However, in the lunar calendar, the date of solar terms is not very easy to determine. Taking the beginning of spring as an example, it can be as early as December 15 of the previous year and as late as January 15 of the new year.and
the ancients in China established 24 solar terms to reflect the changes of seasons and guide agricultural activities. For thousands of years, they have always affected the clothing, food, housing and transportation of thousands of families. However, since 2000, most of China's main political activity centers have been concentrated in the Yellow River Basin, and the 24 solar terms were initially established based on the climate and phenology in this area. China has a vast territory and changeable terrain, so the 24 solar terms are only a reference for many areas outside the Yellow River Basin.
