What is the corresponding date of the 24 solar terms? Thank you.

Every year's solar terms correspond to different dates, but they can be calculated, and there are special calculation formulas.

General formula of longevity -[y× d+c]-l

Y= the last two digits of the year, D=0.2422, L= the number of leap years, and C depends on the solar terms and year.

265438+20th century beginning of spring c value =3.87.

For example: beginning of spring date 20 17.

[ 17×0.2422+3.87]-[( 17- 1)/4]=7.9874-4=3

So the beginning of spring date of 20 17 is February 3rd.

(Note: Only integers are reserved in the calculation results)

Extended data:

The origin of the twenty-four solar terms:

The earth revolves around the sun at 5: 48: 46 every 365 days and rotates once every 24 hours. Because the orbital plane of the earth's rotation is not the same as the equatorial plane, but maintains a certain inclination angle, the position of direct sunlight on the earth is different all year round.

In the northern hemisphere, when the sun is directly at 23.5 degrees north latitude, it is called summer solstice in astronomy; When the sun shines directly at 23.5 degrees south latitude, it is called the winter solstice; The solstice in summer and the solstice in winter mean that it is halfway between summer and winter. Twice a year, when the sun shines directly on the equator, it is the vernal equinox and the autumnal equinox, in the middle of spring and autumn. The day is as long as the night.

Solar terms reflecting the changes of four seasons:

Beginning of spring, Spring Equinox, Long Summer, Summer Solstice, beginning of autumn, Autumn Equinox, beginning of winter and Winter Solstice. Among them, beginning of spring, Changsha, beginning of autumn and beginning of winter are called "Li Si", which means the beginning of the four seasons.

Solar terms reflecting temperature changes:

There are five solar terms: slight summer heat, great summer heat, summer heat, slight cold and great cold.

Solar terms reflecting weather phenomena:

Rain, Grain Rain, White Dew, Cold Dew, First Frost, Light Snow and Heavy Snow are the seven solar terms.

Solar terms reflecting phenological phenomena:

There are four solar terms: fright, Qingming, Xiaoman and Mang.
