The month of July is the seventh month in the Gregorian calendar; it was named for Julius Caesar, the Roman who reformed the calendar in 44 B.C.
July is an important month in the United States because of July 4, the birthday of the nation. It was in 1776, that the Continental Congress, meeting in Philadelphia, adopted the Declaration of Independence. Independence Day is now a legal holiday for all Americans. The United States Independence Day is also observed with ceremonies in England, Norway, Sweden, Denmark, Guatemala, the Phillippines, Canal Zone, and Guam and at all American embassies in foreign lands.
This is one of the most important months for bullfights and the continuance of old customs. An example is the Fiesta de San Fermen at Pamplona in Spain, which is dangerously exciting because the bulls are still allowed to run wild on the streets just before the bullfights, as they did in olden times.
Japan also observes an ancient July Festival associated with four-footed animals. This is a Japanese horse festival that has been held for over six hundred years. It lasts for three days, during which a thousand horsemen clad in ancient armor and helmets joust and compete in archery and horsemanship.
