Thanksgiving Day is celebrated primarily in Canada and the United States on the fourth Thursday of November as a day to give thanks for the harvest and the past year. It has historical roots in religious harvest traditions and was also celebrated in a secular manner. As the first President of the United States, George Washington proclaimed the first nationwide Thanksgiving celebration in America on November 26, 1789 to acknowledge God's favors. Black Friday, the day after Thanksgiving, traditionally kicks off the holiday shopping season in the United States with great discounts followed by Cyber Monday online discounts.
