According to the lunar calendar, January, February, and March were considered spring, April, May, and June were considered summer, July, August, and September were considered autumn, and October, November, and December were considered winter.
The names were given to indicate the weather and the state of living things, and are still used in various situations such as annual events and season’s greetings.
We believe that this is the wisdom of life, which incorporated the sense of the four seasons into our daily lives.
