Happy Columbus Day Weekend. Here's what you need to know for the holiday if you are going to the parade, with a little history to talk about on the way.

History:

Columbus Day celebrates Christopher Columbus' arrival in the United States.

It became a state holiday in Colorado first, in 1906, and became a federal holiday in 1937. Many Italian-Americans observe Columbus Day as a celebration of their heritage. The first occasion was celebrated right here in New York City on October 12, 1866.

In the United States, Hawaii and South Dakota do not celebrate Columbus Day. Instead, they celebrate Discoverers Day (which commemorates the Polynesian discoverers of Hawaii) and Native Americans Day, respectively.

California,Texas and Florida removed Columbus Day as a paid holiday for government workers, while still maintaining it either as a day of recognition or a legal holiday.

Columbus Day is also celebrated in Spain, Uruguay, the Bahamas and many South American countries.
