In December 1941, President Franklin D. Roosevelt signed a bill into law that permanently established the fourth Thursday in November as Thanksgiving Day in the United States. This legislative action followed a period of inconsistent Thanksgiving observance, during which various states celebrated the holiday on different dates. The first national Thanksgiving was proclaimed by George Washington in 1789 but was not fixed to a specific day until this legislation. The change prompted discussions regarding economic strategy and national unity, particularly in the context of the ongoing World War II.

The decision was influenced by debates around consumer behavior and economic relief during a challenging time for the nation. Roosevelt aimed to promote a longer Christmas shopping season to stimulate the economy, hoping that a standardized date for Thanksgiving would encourage families to gather, reflect, and partake in commerce. Additionally, it was essential to create a cohesive national culture during a time of war, with families rallying together in gratitude and resilience. The support for the bill grew from various sectors, emphasizing its advantages from both a cultural and economic standpoint.

After being signed into law, Thanksgiving was officially observed on the fourth Thursday of November each year, contributing to solidifying the holiday’s place in American culture. Many families have since embraced this holiday as a time for gathering, feasting, and expressing thanks, further establishing Thanksgiving as a central part of American tradition. The impact of this legislation extends beyond mere memorization of a date; it influences Thanksgiving practices, family traditions, and even economic patterns in the retail industry.
