Well, according to Google,
today is Earth Day. But if you click on the above graphic, one of the links that pops up is the official site for International Earth Day, which proclaims that Earth Day is Not April 22! Most people in the world celebrate Earth Day on the date of the spring equinox in March. But the mighty steamroller of North American culture has obliterated that inconvenient fact, so many folks in the US and Canada are celebrating it today.
