Japanese season names called shichijuni-ko

The Japanese life culture I introduce today is Japanese season name.
Well, It was very hot from last Friday to last Monday, and I felt a small summer.
It rained from last Tuesday to last Wednesday.
It may be due to the rain, but comfortable temperatures continue from last Wednesday.
[ nijushisekki ]
Well I explained briefly on my blog on February 4 this year about nijushisekki.
In the explanation I introduced nijushisekki as the name of the day dividing the year into 24 equal parts.
The name of nijushisekki is not only the day's name.
It is also a name that represents the period from the day to the next nijushisekki.
In other words, it is also the name of the season that divides the year into 24 equal parts.
In Japan there are the season name of spring, summer, autumn and winter, and the season name of nijushisekki.
This April 20th is the day called "kokuu".
And from April 20th to May 4 this year it is the season called "kokuu".
"Kokuu" is a word connected "koku" and "u".
"koku" means grain.
"U" means rain.
In other words, it means that it is time for starting to rain to grow grain.
So our Japanese ancestor started preparing for rice planting at this time.
There are many farmers still doing it.
I think the rain a few days ago is rain that fell for the grain.
[ shichijuni-ko ]
There is a season name indicating a period shorter than nijushisekki.
We have the shichijuni-ko (72 ko) that divide a year into 72 equal parts in Japan.
The shichijuni-ko on the period from the shunbun to the kokuu is as follows.


I wrote them with Kanji, Hiragana and Alphabets.
Hiragana and Alphabets are long strings.
Because it is not a word but a sentence.
From April 25th to April 29th this year, it is "Shimo yamite nae izuru".
This means "The time when the frost falls is over, and the seedlings of rice comes out."
Other names also show the appearance of that time period in the same way.
We will introduce the remaining shichijuni-ko in another time.
