Has Thanksgiving always been on the same day?

The date set aside for celebration of the Thanksgiving Holiday has changed not once, but twice in U.S. history. President Franklin D. Roosevelt, in order to give depression-era merchants more selling days before Christmas, assigned the third Thursday to be Thanksgiving Day in 1939 and 1940. But he was met with popular resistance, largely because the change required rescheduling Thanksgiving Day events, such as football games and parades. In 1941, a Congressional Joint Resolution officially set the fourth Thursday of November as a national holiday for Thanksgiving.
