Taking five days as a cycle, each cycle corresponds to a phenological phenomenon, which is called "equality". Among them, the plant climate should be germination, flowering, fruiting, etc. Animals should start vibrating, singing, mating, migrating, etc. Abiotic climate should include initial freezing, thawing and thunder. Because the waiting time unit is small (once every five days) and the climate is quite different in different years and regions, it is difficult to be widely used.
