The 22nd of December marks the Winter Solstice for the year of 2018. As one of the 24 solar terms, Winter Solstice is quite unique.
Approximately three thousand years ago, Sage Zhou, one of the greatest politicians, educators, and thinkers in Chinese history, measured the “center of the world” with a stone plate and a needle. After that, through extended observation of the movement of the sun, sagacious Chinese ancestors came up with a system of determining the seasonal alternation by dividing the entire solar period by a factor of 24, which still serves as an important guide for continental monsoon climate agriculture.
As the twenty- second solar term, Winter Solstice is when the daytime is at its shortest and nighttime at its longest. In other words, Winter Solstice occurs when the earth travels around the near-sun point and the sun shines straight on the tropic of Capricorn. Due to the fact that Earth’s orbit around the sun is actually 365 days 5 hours and 48 minutes, the date for the Winter Solstice varies from the twentyfirst to the twenty- third of December, and it is also known as “the day of revival.” After the Winter Solstice, the relative position of the sun travels northward, and daytime in the northern hemisphere increases. “YIN,” the air of darkness starts to decline, while “YANG,” the air of brightness begins to bounce. Because the YANG arises, the Winter Solstice in Chinese is named as the “initial warmth rise.” Consequently, Winter Solstice is when the livelihood of nature is awakened— and a new cycle of the year begins. In this sense, Winter Solstice is known as the “vice new year,” indicating its significant role
