Yom Hashoah

April 21 is the Day of Remebrance for the Holocaust when 6 million Jews and others were killed by the Nazis. It doesn't fall on the same day every year because it's based on the Hebrew calendar.

This is just one of many sites you can find on Google.

Sorry I don't have much time to spend on this right now. I feel like we should all remember the Holocaust, especially with people like the little midget in Iran.
