Thanksgiving is a holiday in the United States and Canada when people give thanks. It is celebrated every year on the fourth Thursday of November in the United States and on the second Monday of October in Canada. In 1863, Abraham Lincoln set aside the last Thursday of November as a national Day of Thanksgiving. American immigrants brought the customs and practices of the American Thanksgiving to Canada, beginning on April 5, 1872. The United States Congress permanently established the fourth Thursday of each November as a national holiday in the year 1941. The Canadian Parliament later established the second Monday of each October as a national holiday in the year 1957. Thanksgiving was originally celebrated to give thanks for the harvest.
