When the longitude of the sun reaches 30 degrees, there will be a festival in Grain Rain. The specific time of Grain Rain in 2022 is Wednesday, April 20th, March 20th, and the first day of Renyin.

The origin of Grain Rain

As a native of China, I am familiar with the traditional 24 solar terms, and Grain Rain is the sixth of the 24 solar terms. Grain Rain is the last solar term in spring, and Grain Rain is taken from the meaning that rain gives birth to hundreds of valleys. In the traditional farming culture, the solar terms in Grain Rain link the valley with the rain, indicating that precipitation and rain produce hundreds of valleys. The biggest feature of Grain Rain is the continuous spring rain, which reflects the significance of Grain Rain's agricultural climate and the reflection of ancient farming culture on festivals. After the solar term in Grain Rain, the temperature rises, the rainfall increases, and the humidity in the air further increases, which is very suitable for the growth of cereal crops. Therefore, ancient farmers should grasp this critical moment when they are engaged in farming activities.

The origin of Grain Rain

The origin of Grain Rain can be traced back to ancient times. "Tongwei Filial Piety Helps the Gods" says: On the 15th day after the Qingming Festival, the bucket refers to Chen, who is Grain Rain. In mid-March, it is said that the rain gives birth to hundreds of valleys, which are clean and bright. "Qunfangpu" also records: Grain Rain, the valley was born because of rain. Before and after Grain Rain, the weather turned warmer and the rainfall increased, which was beneficial to the sowing and growth of spring crops. In the twenty-four solar terms, it is recorded that in the middle of March, the earth and paste pulsated after the rain, and now it rains in the valley. Rain is silent, just like the rain in my field. At this time, cover the grain and sow, from top to bottom. At this time, the weather is mild and the rainfall increases obviously, which has a great relationship with the growth and development of cereal crops. Many crops should be sown at this time.
