Tuesday was a major holiday celebrated the world over, which originated due to events that occurred in Chicago on May 4, 1886. The US is the origin of the holiday, but the holiday is not celebrated in the US. Do you know about the events? If not you can read about them here.
Today is also the anniversary of the killing of 4 students at Kent State University who were shot for expressing their objections to a grossly immoral war. You can read about that here.
I was also told that today is Star Wars Day. May the fourth be with you.
