How many days are there in 49 days?

April 9 is the 29th to 36th day after the winter solstice, a total of nine days.

China has entered a cold day since the winter of November. Astronomical experts say that the Ninth Five-Year Plan is a more applicable solar term in northern China, especially in the middle and lower reaches of the Yellow River.

It started from the day when it met Ren in winter and entered the "number nine", commonly known as "cross nine". From then on, every nine days is called "Nine". After nine "nines", it will be exactly 8 1 day, and then spring blossoms.

In ancient times, especially in northern China, the conditions for working people to keep warm from the cold were simpler than their descendants. The cold winter is regarded as a threat and punishment, which directly affects people's mood and even makes them feel that winter is inexplicably long. At that time, in order to spend the long winter, the people of China invented the method of "counting nine" to pass the time, so as to alleviate the psychological crisis under the threat of winter. At that time, counting nine around family members was also regarded as a carefree realm.
