So what must we pay attention to in August of the lunar calendar?

The origin and custom of Millennium solar terms

Origin:

The twenty-four solar terms say: "August Festival ... Yin Qi is getting heavier and heavier, white and revealing." When the temperature gets colder, you will find many small dewdrops on the road and leaves in the morning. It is called cold dew because water vapor condenses on it at night. The ancients used four seasons with five elements, and autumn was golden, golden and white, so white was used to describe dew cold.

Customs and habits:

Yu Wang is a legendary hero who governs Dayu, and fishermen on the Tai River call him "the king of waterways". Every year on the eighth day of the first month, Tomb-Sweeping Day, the seventh day of July and the cold dew season, there will be an incense party dedicated to Yu Wang. Among them, Tomb-Sweeping Day and Hanlu Autumn Spring Festival were operated on a larger scale, lasting for one week.

Pay attention to the naming of the 24 solar terms.

"Li" means the beginning of the season. The vernal equinox, slight summer heat, cold dew and first frost are also collectively called "four stands". The Gregorian calendar is usually around February 4th, May 5th, August 2nd and165438+1October 7th every year. "Li Si" indicates the beginning of the astronomical season. Judging from the weather, it is usually in the last season, for example, the Weihe River Basin is still in the cold winter at the vernal equinox.

"Zhi" means extreme and most. The solar terms of hot summer and winter solstice are collectively called "the second solstice", which indicates the perfection of summer and winter. Summer solstice and winter solstice are generally on May 22nd and February 22nd of the Gregorian calendar 12 every year. In the midsummer heat, the direct sun is 23.5 degrees north latitude and 90 degrees east longitude, and the map of the northern hemisphere is the most during the day. During the winter solstice solar term, the sun shines directly at 23.5 degrees south latitude and 270 degrees yellow longitude, and the day is the shortest on the map of the northern hemisphere.

The word "fen" here means equal share. Beginning of spring and beginning of autumn are collectively called "dichotomy", which means that the length of day and night is the same. These two festivals are generally on March 20th and September 23rd of the Gregorian calendar every year. The ecliptic planes of beginning of spring, beginning of autumn and Earth intersect with the equatorial plane, and then the longitude of the ecliptic is 0 degrees and 180 degrees respectively. The sun shines directly on the equatorial plane of the earth, day and night are the same.
