Thanksgiving, or Thanksgiving Day, is a holiday celebrated in the United States on the fourth Thursday in November.
It has officially been an annual tradition since 1863, when, during the Civil War, President Abraham Lincoln proclaimed a national day of thanksgiving to be celebrated on Thursday, November 26.[1] As a federal and popular holiday in the U.S., Thanksgiving is one of the major holidays of the year. Together with Christmas and the New Year, Thanksgiving is a part of the broader holiday season.
