FDR Changed the Date of Thanksgiving

For 75 years after Lincoln issued his Thanksgiving Proclamation, succeeding presidents honored the tradition and annually issued their own Thanksgiving Proclamation, declaring the last Thursday in November as the day of Thanksgiving. However, in 1939, President Franklin D. Roosevelt did not. In 1939, the last Thursday of November was going to be November 30. Retailers complained to FDR that this only left 24 shopping days to Christmas and begged him to push Thanksgiving just one week earlier. It was determined that most people do their Christmas shopping after Thanksgiving and retailers hoped that with an extra week of shopping, people would buy more.

So when FDR announced his Thanksgiving Proclamation in 1939, he declared the date of Thanksgiving to be Thursday, November 23, the second-to-last Thursday of the month.

Twenty-three states followed FDR's change and declared Thanksgiving to be November 23. Twenty-three other states disagreed with FDR and kept the traditional date for Thanksgiving, November 30. Two states, Colorado and Texas, decided to honor both dates.

This idea of two Thanksgiving days split some families, because not everyone had the same day off work.

On December 26, 1941, Congress passed a law declaring that Thanksgiving would occur every year on the fourth Thursday of November.
