Thanksgiving Day, a traditional Western holiday, is a holiday unique to the American people and a holiday for American families to get together. In the beginning, there was no fixed date for Thanksgiving, which was temporarily decided by each state in the United States. It was not until 1863, after American independence, that President Lincoln declared Thanksgiving a national holiday. In 1941, the U.S. Congress officially designated the fourth Thursday of November as "Thanksgiving". The Thanksgiving holiday generally lasts from Thursday to Sunday.
Extended information:
The origin of Thanksgiving can be traced back to the beginning of American history, originating from the early immigrants in Plymouth, Massachusetts. These immigrants were called Puritans when they were in the UK. Because they were dissatisfied with the incomplete religious reform of the Church of England, as well as the political suppression and religious persecution of them by the King of England and the Church of England, these Puritans broke away from the Church of England and went to the Netherlands. Later, he decided to move to the uninhabited land on the other side of the Atlantic Ocean, hoping to live religiously and freely according to his own wishes.
