This day celebrates Christopher Columbus’s arrival in the Americas in 1492. As Columbus was Italian, working for Spain, Columbus Day is especially important for many Italian-Americans and Hispanic-Americans. Since 1971, the holiday has been commemorated in the U.S. on the second Monday in October. Officially, the people of the USA are invited to celebrate the anniversary of the discovery of their country with church services and other activities. In some towns and cities, special church services, parades and large events are held.

Most Americans enjoy sports – both playing sports themselves and watching their favourite teams and competitions. Children are encouraged to participate in sports at an early age. The rivalry between high schools and colleges in sporting events goes right through the school year from football in September to track and field in June. Sports are important in college. Students who show talent in a sport like tennis, track and field, swimming, football, or basketball can apply for sports scholarships.
