What day is August 9th?
This year, at 2: 49 p.m. on September 23rd of Gregorian calendar, the ninth day of the eighth lunar month, the sun reaches 180 degrees, and the bucket handle refers to the moment to the right and west, and the autumnal equinox solar terms begin.
The autumnal equinox is the fourth solar term in autumn. The name of this solar term has two meanings. One is that the sun shines directly on the equator that day, and the length of day and night is equal, each being 12 hour, which is the autumn equinox. The second layer means that the autumnal equinox solar terms are in the middle of 90 days in autumn, divided into seasons.
After the autumnal equinox solar terms, the direct position of the sun moves south, and the days become shorter and the nights become longer. The temperature difference between day and night widened and the temperature dropped significantly. The ancients divided 15 days of the autumnal equinox into three periods, namely: the thunder began to stop; Insect blank households; The water began to dry up. Ray is "Yang's voice". The spring equinox solar terms will ring at the beginning of the sun, and will stop at the beginning of the yin after the autumn equinox.
The custom of solar terms in autumn equinox
1. Sacrifice to the Moon for Blessing: In ancient times, our ancestors thought that the sun was the source of yang and the moon was the source of yin, while "the sun is eternal at the vernal equinox and the yin is longer at the autumnal equinox, so the sacrifice is divided into two parts to get the meaning of yin and yang." At the vernal equinox, the yang rises to the ground, and at the autumnal equinox, the yin begins to grow, so the vernal equinox sacrifices the sun to meet the yang, and the autumnal equinox sacrifices the moon to meet the yin.
2. Sacrificing stars for longevity: The autumnal equinox is also a day to worship the "Antarctic Shouxing", also known as the "Old Man Star". It appears around the autumnal equinox every year and disappears before the vernal equinox the following year.
In the early morning of the autumnal equinox, the ancient emperor would lead officials to the southern suburbs outside the city to meet the birthday star of the South Pole, which was called the "Southern Waiting Star". In historical records, there are "Antarctic old people see, public security; Often recorded in the autumnal equinox, such as the southern suburbs.
