15+ Fun Facts About Thanksgiving's Annual Date Changes

Thanksgiving, a beloved holiday celebrated across the United States, has an intriguing history that includes annual date changes. These date adjustments have played a significant role in shaping the traditions and experiences associated with this festive occasion. From its origins to the present day, the evolution of Thanksgiving's date has resulted in a fascinating tapestry of cultural and historical influences. In this article, we delve into 15+ captivating facts about the annual date changes of Thanksgiving, offering a unique perspective on this much-loved holiday.
The Early Days of Thanksgiving Date Flexibility

The history of Thanksgiving’s date changes can be traced back to the 18th century, a time when the celebration of this holiday was not yet standardized. During this era, Thanksgiving was primarily a religious observance, and its date was often determined by regional customs and the preferences of individual colonies or states.
One of the earliest known instances of Thanksgiving date flexibility occurred in 1777. Following the American victory at the Battle of Saratoga during the Revolutionary War, the Continental Congress declared a national day of thanksgiving to be held on December 18th. This marked the first time that a national Thanksgiving celebration was organized, albeit on a one-time basis.
In the years that followed, individual states continued to observe Thanksgiving on various dates throughout the year. For instance, in 1789, President George Washington issued a proclamation designating the last Thursday in November as a day of national thanksgiving. However, this proclamation was not legally binding, and many states continued to celebrate Thanksgiving on different days.
The Influence of Sarah Josepha Hale
One of the most significant figures in the history of Thanksgiving date changes was Sarah Josepha Hale, a renowned author and editor. Hale, known for her advocacy for women’s education and her contributions to literature, played a pivotal role in shaping the future of Thanksgiving.
In the mid-19th century, Hale began a tireless campaign to establish Thanksgiving as a national holiday. She wrote numerous editorials and letters to politicians, urging them to standardize the date of Thanksgiving. Hale believed that a nationally recognized Thanksgiving would foster a sense of unity and gratitude among Americans.
Her efforts paid off in 1863 when President Abraham Lincoln issued a proclamation declaring the last Thursday in November as a day of national thanksgiving. This proclamation, influenced by Hale's advocacy, marked a significant milestone in the history of Thanksgiving and set the stage for future date changes.
The 20th Century: A Decade of Date Changes

The 20th century saw a series of date changes for Thanksgiving, primarily driven by economic considerations and the desire to extend the holiday shopping season.
The Franklin D. Roosevelt Era
In 1939, President Franklin D. Roosevelt made a controversial decision to move Thanksgiving up by a week. The traditional date of the last Thursday in November fell on November 30th that year, leaving only 24 shopping days until Christmas. Retailers feared that this would negatively impact holiday sales, prompting Roosevelt to issue a proclamation changing the date to the second-to-last Thursday in November.
This decision, known as the "Franksgiving" controversy, sparked widespread debate and criticism. Many Americans, particularly those in New England, felt that the date change disrupted longstanding traditions and undermined the significance of Thanksgiving. Despite the controversy, Roosevelt's proclamation stood, and Thanksgiving was officially celebrated on November 23rd in 1939.
The following year, in 1940, Roosevelt again moved Thanksgiving up by a week, setting the date for November 21st. However, this decision faced even greater opposition, with 22 states refusing to comply and opting to celebrate Thanksgiving on the traditional last Thursday in November.
In 1941, Congress intervened and passed a joint resolution, officially setting the date of Thanksgiving as the fourth Thursday in November. This resolution, signed into law by President Roosevelt, resolved the date controversy and established a consistent date for Thanksgiving moving forward.
The Modern Era: A Stable Date
Since the passage of the 1941 joint resolution, Thanksgiving has been celebrated on the fourth Thursday in November, with very few exceptions. This stable date has allowed for the development of enduring traditions and has become a cornerstone of the American holiday season.
However, it's worth noting that there have been rare instances where Thanksgiving has been celebrated on a different date. For example, in 1956, Thanksgiving was observed on the fifth Thursday in November due to a quirk in the calendar. Similarly, in 2020, Thanksgiving fell on the fifth Thursday in November, but this was a result of the leap year rather than a deliberate date change.
Thanksgiving’s Impact on Retail and the Economy
The date changes of Thanksgiving have had a significant impact on the retail industry and the overall economy. The extension of the holiday shopping season, made possible by the date changes, has become a critical period for retailers, as it accounts for a substantial portion of their annual sales.
The additional week between Thanksgiving and Christmas provides retailers with an opportunity to offer early discounts and promotions, attracting consumers and driving sales. This extended shopping season has become a key driver of economic growth, particularly in the retail and hospitality sectors.
Black Friday and Cyber Monday
The date changes of Thanksgiving have also played a role in the emergence of Black Friday and Cyber Monday, two of the most significant shopping days of the year. Black Friday, the day after Thanksgiving, has become synonymous with massive discounts and doorbuster deals, as retailers aim to capitalize on the extended shopping season.
Similarly, Cyber Monday, which falls on the Monday after Thanksgiving, has become a major online shopping event. Retailers offer online-exclusive deals and promotions, attracting tech-savvy consumers and further extending the holiday shopping season.
The Future of Thanksgiving Date Changes
Looking ahead, it is unlikely that there will be any significant date changes for Thanksgiving in the foreseeable future. The fourth Thursday in November has become a well-established tradition, and any attempts to alter this date would likely face significant opposition.
However, it is worth noting that the date of Thanksgiving can vary slightly from year to year due to the intricacies of the calendar. For instance, in 2021, Thanksgiving fell on November 25th, which was the fifth Thursday in November. This variation is a result of the leap year cycle and the alignment of the calendar with the astronomical seasons.
A Day of Gratitude and Family
Regardless of the date, Thanksgiving remains a cherished holiday for Americans, a time to gather with family and friends, share a meal, and express gratitude for the blessings in their lives. The traditions associated with Thanksgiving, such as the iconic turkey dinner, football games, and parades, have become an integral part of the American cultural fabric.
Thanksgiving serves as a reminder of the importance of community, generosity, and reflection. It is a time to come together, to put aside differences, and to celebrate the spirit of gratitude that lies at the heart of this beloved holiday.
Conclusion

The annual date changes of Thanksgiving have shaped the history and traditions of this iconic holiday. From its early days as a flexible religious observance to the standardized fourth Thursday in November, Thanksgiving has evolved to become a cornerstone of American culture. The date changes, driven by a combination of historical, cultural, and economic factors, have played a significant role in shaping the modern-day celebration of Thanksgiving.
