There are "three summers" in the 24 solar terms, namely, little summer, big summer and long summer, followed by early summer, heatstroke and late summer. There is also a "beginning of autumn" solar term in the middle of the "Three Summers". After beginning of autumn, it is summer, and the heat lasts for a long time. Long-term intense heat is beneficial to the growth and yield of crops. The ancients called the period from beginning of autumn to the autumnal equinox "long summer".

The dog days include four solar terms: Slight Summer, Great Summer, beginning of autumn and Summer. By the time of the heat, the dog days have passed or ended.
