2 - Thanksgiving or Thanksgiving Day
It is a public holiday celebrated on the fourth Thursday of November in the United States. It originated as a harvest festival. Thanksgiving has been celebrated nationally on and off since 1789, after Congress requested a proclamation by George Washington. It has been celebrated as a federal holiday every year since 1863, when, during the American Civil War, President Abraham Lincoln proclaimed a national day of "Thanksgiving and Praise to our beneficent Father who dwelleth in the Heavens," to be celebrated on the last Thursday in November. Together with Christmas and the New Year, Thanksgiving is a part of the broader fall/winter holiday season in the U.S.
The event that Americans commonly call the "First Thanksgiving" was celebrated by the Pilgrims after their first harvest in the New World in October 1621. This feast lasted three days, and it was attended by 90 Native Americans and 53 Pilgrims. The New England colonists were accustomed to regularly celebrating "thanksgivings"—days of prayer thanking God for blessings such as military victory or the end of a drought.
