What a great source of information! The Earth Calendar, a virtual date book of holidays around the world, is an enormous storehouse of information. If you want to know what's going on in the world on any date, just search the calendar. You can search by country or religion, too. The site's layout is cute -- it looks like a date book -- but the navigation is a little confusing. But hey, now we have a reason to celebrate July 29 -- it's the Norse Festival of Thorr.
