Lunar calendar day in winter?

Winter solstice is one of the 24 solar terms.

Don't use the date of the lunar calendar to calculate! ! First of all, we should know that the new calendar = solar calendar.

In ancient times, westerners used the positions of the earth and the sun to determine the date.

So it's called the solar calendar! ! contrary/opposite

China people use the positions of the earth and the moon to determine the date! Therefore, the lunar calendar = lunar calendar and solar terms (section = section/gas = weather) are divided according to the position on the earth's orbit.

Describe the natural phenomenon of the earth caused by the sun! ! The earth goes around the sun 360 degrees a year.

Divide 360 degrees into 24 parts.

Each serving is 15 degrees.

15 degree is a solar term.

Each solar term is about 15 days.

Uh-huh, make up twenty-four solar terms! ! Because the 24 solar terms are divided by the orbit of the earth's revolution.

Therefore, the date of the same solar calendar will be close to the frame! !

The winter solstice is the most important of the 24 festivals in a year. Its origin is directly related to the calendar. The date of winter solstice is usually1February 22nd in the solar calendar every year; The date of the lunar calendar is not fixed, but it generally does not exceed November of the lunar calendar.

The two bosses upstairs both spoke 7788. I just add one thing: according to the family's winter solstice, the solar calendar is1February 2 1 day or 22nd every year, but it has been two days in the last 40,500 years. From the Mayan ruins in Central America, it was found that 8,000 years ago, it arrived in Hibii a few days earlier in winter, because the angle of the earth's rotation axis was 24 degrees to 24 degrees, that is, the latitude of the Tropic of Capricorn was 24 degrees to 24 degrees. In other words, it has not been decided whether the winter solstice is on1February 24th or 25th. In a few thousand years, the winter solstice may not be fixed until1February 19 or 20, when the tropic of cancer will be 22 degrees north and 23 degrees south latitude.

The winter solstice is one of the 24 solar terms in the China lunar calendar. The earth moves around the sun, and the position of the sun relative to the earth is different every day. This imaginary orbit is called the ecliptic. Twenty-four solar terms are 24 different positions of the sun on the ecliptic (each position is different by 15 degrees). The days when solar terms appear are quite stable, usually within three days around a certain date. Astronomically speaking, the winter solstice is a day when the sun shines directly on the Tropic of Capricorn, and it is also the shortest sunshine day in the northern hemisphere. After the winter solstice, the position of direct sunlight began to move northward, and the sunshine time in the northern hemisphere began to increase.
