"The May Festival means that the grains with awns in them can be planted." This is how the name Grain in Ear came about. It has a very down-to-earth meaning, but from a meteorological point of view, this solar term is too restless: there is abundant rainfall, the temperature rises significantly, and common weather disasters include tornadoes, hail, strong winds, heavy rains, droughts, etc. The Gregorian calendar date of Grain in Ear is usually around June 6 or 7 of the Gregorian calendar every year, when the sun reaches 75° of the ecliptic longitude.
In North China, there is a saying that "Grain in Ear wheat comes before April and Grain in Ear wheat comes after May". This is caused by the lunar calendar algorithm. According to the lunar calendar, a year is actually 354 or 355 days. This is 10-11 days less than the number of days it takes for the Earth to orbit the sun, so a leap year must be added every three years (sometimes every two years) to make up for the missing days. During a leap month, the solar term is either advanced or postponed, so Grain in Ear is sometimes in April and sometimes in May. Chinese farmers are well aware that Grain in Ear in April comes early as the spring begins and the solar term is pushed forward, so they plant crops early, before Grain in Ear. If it is Grain in Ear in June, the crops will be planted after the solar term.
