Thanksgiving is a very American holiday. It is also called Thanksgiving Day. It is celebrated on the fourth Thursday in November every year. It used to be a religious holiday to give thanks to God. There are two versions of the origins of this holiday. One is thanks for the early settlers arriving in America safely. On December the 4th, 1619, a group of English pioneers arrived at a place called Berkeley Hundred, in Virginia. The group made a promise that the day of their arrival should be a "day of thanksgiving" to God. The second version is the thanks given to Native Americans for teaching the pilgrims how to catch eels and grow corn in Plymouth, Massachusetts. In 1941, President Roosevelt made Thanksgiving a federal holiday.
