The first day of spring

 Gardenia;(Ku-chi-na-shi)

Today is one of the 24 ｓeasonal datum points called 'Ri-sｈu-n'; the first day of spring.　　
It'll be warmer and warmer from this time of the year.
In fact, it was very warm today, especially in the daytime.

But actually February is the coldest month of the year, so we call this month 'Ki-sa-ra-gi' in Japanese that means we put on clothes more. 

Three cold days and four warm days will be repeated for the time being till warm spring comes.
We might get colds because of this weather.

So please take care !
