On the winter solstice, the sun is located at 270 degrees longitude, and the sun shines almost directly on the Tropic of Capricorn. It is the shortest day of the year in the northern hemisphere. Correspondingly, the southern hemisphere has the longest day of the year on the winter solstice.

In date-selection studies, auspicious lessons are selected based on the solar terms of the lunar calendar. The so-called lunar calendar is a combination of the solar calendar and the lunar calendar. The solar calendar refers to the twenty-four solar terms (dividing the cycle of the sun into twelve stages, and then dividing the twenty-four solar terms into one month.), while the lunar calendar is a pure month (according to the movement of the moon) ), the days are on the 22nd or 23rd of December in the Chinese calendar.
