The awn seed is in the vigorous season, and it is the time when the wheat is ripe. The wheat waves in the field are rolling and golden. From this day on, it is the most intense period of sowing.

In ancient China, mango seeds were divided into three stages: "One stage was when mantis was born; Second, wait for Peng to start singing; The third-class tongue is silent. " In this solar term, the eggs laid by mantis in late autumn last year, because they felt the birth of Yin Qi, broke their shells and gave birth to little mantis; Shady shrike birds began to appear in the branches and sing in the shade; On the contrary, mockingbirds, who can learn from the songs of other birds, stop singing because they feel the appearance of Yin Qi.

Interpretation of the formula: Y= two digits after the number of years, D=0.2422, L= leap year, 2 1 century C=5.678, and 20th century =6.5.

For example, the date of the awning in 2088 = [88× .0.2422+5.678]-[88/4] = 26-22 = 4, and the awning on June 4.

Exception: 1902 plus 1 day.
