Basketball is one of the most watched and played sports in America, and it is quickly growing in popularity around the rest of the world. Basketball can be played inside or outside with little equipment. All you need is a hoop, which can be found at most parks and gyms, so anyone can play basketball at any time of year. Basketball Day is a day for all of basketball’s fans to celebrate its invention and the way it has affected the world ever since. This holiday is celebrated on the birthday of James Naismith, a Massachusetts P.E. teacher who invented basketball as a sport that his students could play inside during the winter.
