Hello World Day (November 21, 1973)
Greet ten people on this day for peace. So far over 180 countries have participated in this simple day. The holiday was started as a response to the fighting between Egypt and Israel. If we get to know each other, perhaps we will refrain from killing each other. To read letters from people all over the world, read the Hello World Letters
