Did you know that before the 1940s Thanksgiving was not on a fixed date but was whenever the President proclaimed it to be?

Franklin D. Roosevelt’s Presidency, Thanksgiving was not a fixed holiday; it was up to the President to issue a Thanksgiving Proclamation to announce what date the holiday would fall on. Tradition had dictated that the holiday be celebrated on the last Thursday of the month, however, this tradition became increasingly difficult to continue during the challenging times of the Great Depression.

Roosevelt’s first Thanksgiving in office fell on November 30, the last day of the month, because November had five Thursdays that year. This meant that there were only about 20 shopping days until Christmas and statistics showed that most people waited until after Thanksgiving to begin their holiday shopping. Business leaders feared they would lose the much-needed revenue an extra week of shopping would afford them. They asked President Roosevelt to move the holiday up from the 30th to the 23rd. He chose to keep the Thanksgiving holiday on the last Thursday of the month, however, as it had been for nearly three-quarters of a century.

In 1939, with the country still reeling from the effects of the Great Depression, Thanksgiving once again threatened to fall on the last day of November. This time President Roosevelt did move Thanksgiving up a week to the 23rd. Changing the date seemed harmless enough, but it proved to be quite controversial. Small business owners felt it put them at a disadvantage and they sent letters of protest to the President.

As opposition grew, some states took matters into their own hands and defied the Presidential proclamation. Some Governors declared November 30th as Thanksgiving. And so, depending upon where one lived, Thanksgiving was celebrated on the 23rd and the 30th. This was worse than changing the date in the first place. Families who lived in states such as New York did not have the same day off as family members in states such as Connecticut! Family and friends were unable to celebrate the holiday together.

President Roosevelt observed Thanksgiving on the second to last Thursday of November for two more years, but the amount of public outrage prompted Congress to pass a law on December 26, 1941, ensuring that all Americans would celebrate a unified Thanksgiving on the fourth Thursday of November every year.

So, Happy Thanksgiving to everyone — Thursday, 28 November 2013!
