24 Sekki / 24節気 

~ 24 Divisions of The Solar Year; 24 Terms Used to Denote The Changing of The Seasons ~

What IS 24 Sekki?

 

A year is divided into four seasons But here in Japan, There is also a calendar to divide a year into 24 sections.

It is called “24 Sekki (24節気).

 

In days long gone, people needed to know when to sew fields, when to harvest and other things related to living with nature and the changing seasons.

 

24 Sekki (the twenty-four divisions of a year) is originally from China.

In old China, people also had troubles with the gap between their calendars and the actual seasons.

People needed to accurately know the seasons’ transitions,

and that’s why the 24 sekki was invented.

 

It came to Japan in the 6th century.

However, some of the Chinese seasons don’t match Japanese seasons,

so zassetsu (雑節 / specific days for seasons other than the twenty-four divisions of a year) was added on Japanese calendars.
