What time is the winter solstice in 2018?

Saturday, December 22, 2018 06:21:42 (the 16th day of the winter month in the Year of the Dog, 11 days away from the 2018 Winter Solstice)
The winter solstice falls between December 21 and 23 of the Gregorian calendar every year. It is worth noting that because the earth is near its perihelion around the winter solstice and moves slightly faster, the time the sun shines directly on the southern hemisphere is about 8 days shorter than the time it shines directly on the northern hemisphere in a year. Therefore, the winter in the northern hemisphere is slightly shorter than the summer. The ancients said: When yin reaches its extreme, yang begins to be born, the sun reaches its southernmost point, the day is at its shortest, and the shadow is at its longest, so it is called "Winter Solstice". The ancients believed that from the winter solstice, the yang energy of heaven and earth began to rise and become stronger, that is, the next cycle began. The winter solstice is when yang is born and the yang energy of heaven and earth rises, which is a "lucky day."

Is the Winter Solstice calculated according to the lunar calendar or the solar calendar?

The winter solstice is calculated according to the solar calendar.
When the sun reaches 270° of the ecliptic longitude, the winter solstice falls on December 22 every year. If it is a leap year, it will be moved forward one day to December 21. The 24 solar terms are a supplementary calendar established in ancient China to guide agricultural activities. It was formed during the Spring and Autumn Period and the Warring States Period. The 24 solar terms are determined based on the sun's movement cycle, so the dates of the 24 solar terms are all based on the Gregorian calendar.
