Puritans set the precedentThe concept of Thanksgiving is rooted in the United States’ puritan past. At first no particular day of the week was reserved for Thanksgiving, but some days thought more appropriate than others. Abraham Lincoln made Thanksgiving more about appreciating the privilege of living in a democracy, rather than paying tribute to the almighty. Also on Oct. 3, Lincoln issued a proclamation declaring Thanksgiving an annual holiday to take place on the last Thursday of November. So, there definitely is a reason you’ve celebrated Thanksgiving on the same day of the month your whole life.
