February 14 is Valentine day. Its origin is in ???? anyway not in Japan. It is the day to show love to every one, or in Japan to show women's love to men.
And we ( not me) made some interesting days.
For example March 14 is White day. It is the day to show love to men to women. Though on Valentine day usual women give chocolate to men, on White day women tend to ask more expensive things from men. ( I forgot what I got from Yuki, probably " a little bit " expensive cake" I think.)
The preceding paragraph was too long, sorry.
And today May 13 is May storm day. Of course it is made in Japan.
It is the day to say good by to your lover. It is the 88th day from Valentine day.
Here in Japan we have such phrase, "the last frost before the end of spring (it means the eighty-eighth day from the beginning of spring) ". We can say goodbye to cold winter on the day. We love to use 88 describe season or weather.
May storm day seems to come from this phrase.
If you want to discard something, or say good bye to someone, today may be a suitable day.
Now it's past 7 PM.
Unfortunately I seem not to have used this day effectively.
