Oh, my son has been sick since two days ago. I miss him and I definitely will read him a story book after I get off work. I've resteemed this post for him. I didn't know this info. In Taiwan, it is April 4. Very interesting number coincidence. 44 and 55.
That's interesting. Japan's day was adopted from China hundreds of years ago, and there is a reason that it is the fifth day of the fifth month, but I don't really understand the explanation that I was given-a mix of word play, old beliefs, and the lunar calendar.
