Twenty-four solar terms songs, each on the month and day of the solar calendar.

Song of the Twenty-Four Solar Terms: Spring rain shocks the clear valley sky in spring, summer is full of awns and summer heat is connected, autumn is dew, autumn is cold and frost falls, winter is snowing, and winter is cold.

The beginning of spring: February 4-5, which is the beginning of spring.

Rain: February 18th to 20th, when winter turns to spring, the temperature begins to rise, and the air humidity continues to increase, but cold air activities are still very frequent.

The Waking of Insects: March 5th (6th), refers to the hibernating organisms that have been hibernating in the soil in winter and start to move. Before and after the Waking of Insects, it is cold and warm at first, and the temperature and wind change greatly.

Vernal Equinox: On March 20 (or 21) every year, the sun shines directly on the equator, and the day and night are almost equal in length. Overwintering crops in vast areas of my country will enter the spring growth stage.

Qingming: On April 5th (or 4th) every year, the temperature rises and the weather gradually becomes warmer. Grain Rain: Around April 20, the rain increases, which is beneficial to the growth of cereals.

The beginning of summer: May 5 or 6 is the "beginning of summer". All things grow and thrive.

Xiao Man: May 20 or 21 is called "Xiao Man". The grains of summer-maturing crops such as wheat begin to be full at this time, but are not yet mature.

Manzhong: Around June 6, when the sun moves to 75 degrees of ecliptic longitude. Wheat and other awning crops are mature and seeds can be collected.

Summer Solstice: Around June 22, the sun shines directly on the Tropic of Cancer, and "the sun reaches the north, the sun reaches the longest, and the shadow of the sun reaches the short" appears, so it is called the "summer solstice".

Slight Heat: Around July 7, the summer heat begins, marking the entry of the hot season in most areas of our country.

Great Heat: around July 23, around the time of mid-summer. This period is the hottest period of the year in most areas of our country, but there are also abnormal years where "the heat is not hot" and there is too much rain.

Beginning of Autumn: On August 7th or 8th, the vegetation begins to bear fruit, and it is the harvest season. End of Heat: August 23 or 24, "End" means end, when the summer heat is about to end and the weather will become cooler. Since it is the time of autumn harvest, precipitation is very precious.

White Dew: Around September 8, due to the obvious shift of the direct sun point to the south, the temperature in various places dropped rapidly, the weather was cool, and the water vapor close to the ground formed white dew on the vegetation at night, hence the name "White Dew".

Autumn Equinox: Around September 22, the direct sunlight returns to the equator, making day and night equal in length.

Cold dew: around October 8. At this time, the direct point of the sun continues to move south, the temperature in the northern hemisphere continues to drop, the weather becomes colder, and the dew is very cold, so it is called "cold dew wind".

Frost Descent: "Frost Descent" occurs around October 23. The first frost period in the Yellow River Basin is generally in late October, which coincides with the "Frost Descent" season. Frost is very harmful to growing crops.

Beginning of Winter: around November 7th every year.

Xiaoxue: Around November 22nd is the "Xiaoxue" solar term. The cold air in the north is strengthening, the temperature is dropping rapidly, and snowflakes appear in the precipitation. However, this is the first snow stage, the amount of snow is small, and the frequency is not many. Snow mostly falls after the "light snow" solar term in the Yellow River Basin.

Heavy snow: around December 7. At this time, the direct point of the sun is close to the Tropic of Capricorn, and the days are short and the nights are long in the northern hemisphere.

Winter Solstice: Around December 22, when the sun almost shines directly on the Tropic of Capricorn, the northern hemisphere forms the southern solstice, the short sun solstice, and the long shadow solstice, making it the shortest day of the year. After the winter solstice, the days in the northern hemisphere become longer and the temperature continues to drop, reaching the lowest temperature of the year.

Snowy Cold: Around January 5, the climate starts to get cold.

Big Cold: Around January 20, it is the coldest time of the year.
