Q: Thanksgiving has traditionally been the start of the Christmas season in the U.S. Which U.S. President moved Thanksgiving back a week to extend the holiday shopping season?
A: Franklin Delano Roosevelt made the move in an attempt to help out retailers suffering through the Depression. Since 1859 U.S. Thanksgiving had been celebrated on November 30th, but in 1939 FDR declared the holiday to be the fourth Thursday in November (November 23 of that year). Two years later FDR signed a bill making the move permanent and official.
