How to remember the formula of 24 solar terms?

Section 24 quick memory method is as follows:

Formula 1: Spring rain shocks spring and bright valley days, summer is full of mans, and summer is even. Autumn dew, autumn frost, little snow in winter and cold in winter.

Formula 2: Spring rain shakes the valley in spring, and summer is full of mountain heat. Autumn dew, autumn frost, little snow in winter and cold in winter. The first half of the year is June 2 1 day, and the second half is August 23. The dates of the two festivals each month are fixed, with a maximum difference of one or two days.

Formula 3: A slight cold is followed by a severe cold in January, and it will rain in the early spring of February. March of vernal equinox, April of Qingming Grain Rain. May is Changxia and Xiaoman, and June is the summer solstice company. In July, there was a slight summer heat and a great summer heat, while in August, beginning of autumn was in the midst of a summer heat. In September, the Millennium meets the autumnal equinox, and the first frost and cold dew are all in October. There is a light snow in 1 1 month in beginning of winter, and a heavy snow in winter solstice to welcome the New Year.

Formula 4: Plum blossoms in beginning of spring are particularly bright, and apricot blossoms in rain are particularly fresh. Lulin thunder, butterfly dance between flowers at the vernal equinox. The Qingming kite was broken, accompanied by Grain Rain's tender tea and emerald. Mulberry fruits are like cherries in the long summer, and silkworms are cultivated in the small man. Before mango seedlings were sent to the courtyard, the summer solstice rice fragrance was like a white convention. Summer breeze urges early-maturing beans, and Chi Pan enjoys red lotus in hot summer. Qiu Chan makes people sleep, and sunflower smiles in summer.

The white dew returns to the geese, and the autumn equinox smells like osmanthus. Cold dew vegetable seedlings are green, and the first frost reed flowers are floating all over the sky. Beginning of winter reported good news, reported three rewards, and light snow and goose feathers flew in pieces. The snow is very cold, the plum blossoms are crazy in the wind, and the winter solstice is full of snow. Little cold wanderers are homesick, and they celebrate reunion at the end of the cold year.

Pay attention to the naming of the 24 solar terms.

Twenty-four solar terms reflect the apparent movement of the sun in one year, so the dates of solar terms are basically fixed in the current Gregorian calendar, with the first half of the year being 6 days and 2 1, and the second half being 8 days and 23 days, with a difference of 1 ~ 2 days.

"Li" is the beginning of all seasons, and four "Li" in spring, summer, autumn and winter are the beginning of four solar terms. For example, beginning of spring means the beginning of spring.

Beginning of spring, Changsha, beginning of autumn and beginning of winter are also called "four seasons". The Gregorian calendar is generally around February 4th, May 5th, August 7th and165438+1October 7th every year. "Li Si" indicates the beginning of the astronomical season. As far as climate is concerned, it is still in the last season. For example, the Yellow River Basin in early spring is still in the middle of winter.

"Zhi" means extreme and most. The summer solstice and the winter solstice are called "the second solstice", which indicates the arrival of summer and winter. Summer solstice and winter solstice are generally on June 2 1 day and February 22 12 of the Gregorian calendar every year. On the summer solstice, the direct sunlight is 23.5 degrees north latitude and 90 degrees yellow longitude, which is the longest day in the northern hemisphere. On the solstice in winter, the direct sunlight is 23.5 degrees south latitude and 270 degrees yellow longitude, and the daytime in the northern hemisphere is the shortest.

"Points" here means equal distribution. The vernal equinox and autumnal equinox are called "equal share", which means that the length of day and night is equal. These two solar terms are generally around March 20 and September 23 of the Gregorian calendar every year. At the vernal equinox and autumnal equinox, the ecliptic intersects the equatorial plane. At this time, the ecliptic is 0 degrees and 180 degrees respectively, and the sun shines directly on the equator, and day and night are equal.
