July in the northern hemisphere is a month for heat, celebration, and fun. Pagan celebrations abound. In the United States, the Fourth of July heralds Independence Day, a national celebration of freedom gained in part through the signing of a formal document that explains why a group of colonies broke away from their colonizers. The Declaration of Independence is a representation of choice and has been used as a model for other countries around the world. The spirit of such a document is celebrated annually with feasting, fireworks, and flags.
