In the United States, Thanksgiving is observed on the fourth Thursday in November. In 2026, that falls on November 26. For many families it is a day to gather, share food, and express gratitude. Its history is more complicated than a simple story about the beginning of a yearly dinner.
What happened in 1621?
A harvest gathering at Plymouth involving English colonists and Wampanoag people in 1621 became central to the popular Thanksgiving story. The National Museum of the American Indian’s “First Thanksgiving” resource asks readers to examine that story through documents, public images, and Wampanoag perspectives.
The gathering took place within relationships shaped by diplomacy, disease, settlement, and competing interests. A brief meal narrative cannot stand in for that larger history. The museum’s materials help distinguish the event from later depictions of it, and remind readers that Native communities are part of the present as well as the past.
How a national holiday developed
The modern holiday did not continue unchanged from 1621. The Library of Congress describes several strands behind Thanksgiving, including local observances and national days of thanksgiving. Its account also notes that Abraham Lincoln’s 1863 proclamation did not mention the Plymouth gathering.
Writer and editor Sarah Josepha Hale advocated for a national Thanksgiving observance. Her September 1863 letter to Lincoln is discussed in the Library’s Thanksgiving classroom materials. That autumn, during the Civil War, Lincoln proclaimed a national day of thanksgiving and praise.
Why the fourth Thursday?
The calendar rule came later. After disagreement over moving the observance to an earlier November Thursday, Congress acted in 1941. The National Archives documents the resolution signed by President Franklin D. Roosevelt on December 26, 1941, establishing the fourth Thursday of November as the federal holiday.
That is why Thanksgiving sometimes falls relatively early in the month and sometimes near its end. It is a weekday-based observance, not a fixed November date.
More than one perspective
Thanksgiving does not carry the same meaning for everyone. The National Museum of the American Indian’s Native perspectives on Thanksgiving challenges the familiar simplified narrative. Its historical timeline includes the National Day of Mourning and places the holiday within a much longer Wampanoag history.
For a family gathering, this can be an invitation to learn rather than stage a reenactment. Read a source together, name the particular Native nation in the story, and avoid treating a single costume or image as a representation of many different peoples.
A thoughtful celebration today
You can make gratitude practical: recognize someone’s help, share hosting work, or give a guest an easy way to contribute. A meaningful meal does not require elaborate decorations. Our hosting checklist and simple activities offer ways to make space for conversation and time together.
