"six Yin dissipate and one Yang grows. It is hidden and sprouting. The snowflakes are light. The rivers and seas are frozen in September." Yin Zhiping's "one Yang grows" in the Yuan Dynasty refers to the winter solstice, an important solar term in the Chinese lunar calendar and a folk festival with a long folk history. Then let the old yellow calendar introduce you to what time is the winter solstice in 2018.

therefore, the winter solstice is the day with the shortest day and the longest night in the northern hemisphere, and the farther north, the shorter the day and the longer the night. North of the Arctic Circle, the sun is below the horizon all day, making it the most extensive day of polar night in the northern hemisphere. For all parts of the northern hemisphere, the winter solstice is also the day with the lowest noon sun height all year round.


it is worth noting that before and after the winter solstice, the earth is located near the perihelion and runs slightly faster, which makes the time of the sun in the southern hemisphere about 8 days shorter than that in the northern hemisphere. Therefore, the winter in the northern hemisphere is slightly shorter than that in summer.

ancient health preservation and exercise attached great importance to the period when Yang Qi was born. It is considered that when Yang Qi is born, it should be protected and nursed carefully, just like farmers raising seedlings and women getting pregnant, so as to make it grow gradually. Because only when there is sufficient Yang in the human body can the purpose of eliminating diseases and prolonging life be achieved. Therefore, Zishi and ziyue, like the winter solstice, play an important role in traditional health preservation.
