When is winter?

The day from winter to Sunday is winter, and the time is between February 22nd and 23rd in 65438 Gregorian calendar.

The winter solstice is a very important solar term, and it is also a traditional festival in China's lunar calendar. Up to now, there are still many places where the winter solstice festival is held. The winter solstice is commonly known as "Winter Festival", "Dragon Solstice Festival" and "Asian New Year Festival". As early as 2500 years ago, during the Spring and Autumn Period, China had determined the winter solstice by observing the sun through the soil return, which was the earliest of the 24 solar terms. The time is between February 22nd and 23rd of Gregorian calendar 12.

The winter solstice is the year with the shortest day and the longest night in the northern hemisphere. After the solstice in winter, the days will get longer day by day. The ancients said this about the winter solstice: As soon as the cathode arrived, the yang began to grow, the sun went south, the day was short and the shadow was long, so it was called "the winter solstice". After the solstice of winter, the climate everywhere has entered the coldest stage, which is what people often say.

Winter solstice:

The winter solstice is one of the 24 solar terms, which is opposite to the summer solstice, and the time is around 65438+February 22 of the Gregorian calendar every year. At this time, the sun reached 270 degrees. On the solstice in winter, the direct sunlight reaches the southernmost point of the year, almost directly on the tropic of Capricorn. On this day, the northern hemisphere gets the least sunshine and the shortest day. The farther north, the shorter the day.

Similarly, it is also because the sun has the lowest height and the shortest sunshine time from winter to morning, and the heat absorbed by the ground is less than the heat lost, so the weather is generally cold. Count to nine from the solstice in winter, and every nine days is a nine. By the time of "99", the weather turned warmer, and most parts of the country entered spring, which is also commonly known as "99 sunny day".
