Thanksgiving 2026 is on Thursday, November 26. Under federal law, the holiday is always the fourth Thursday of November, so it can fall anywhere from November 22 to November 28.
Lincoln’s last Thursday
In 1863, during the Civil War, Abraham Lincoln proclaimed a national day of thanksgiving on the last Thursday of November. Presidents kept issuing a proclamation each year, and the last Thursday became the custom.
The 1939 problem
November 1939 had five Thursdays. With the country still recovering from the Great Depression, retailers worried that a late Thanksgiving would shorten the holiday shopping season. President Franklin D. Roosevelt moved the holiday one week earlier, to the fourth Thursday.
Not every state went along. For the next few years, some states celebrated on the president’s date and others kept the traditional one, and critics nicknamed the earlier date ‘Franksgiving’.
Congress settles it
In late 1941, Congress passed a resolution fixing Thanksgiving as the fourth Thursday in November, and Roosevelt signed it on December 26, 1941. The rule took effect in 1942 and has not changed since.
Why it matters today
Because the date is fixed by day of the week, the shopping season between Thanksgiving and Christmas changes length from year to year. In 2026, with Thanksgiving on November 26, there are 29 days until Christmas.
Before Lincoln
The holiday’s roots are usually traced to 1621, when the Plymouth colonists and the Wampanoag people shared a harvest feast that lasted several days. It wasn’t called Thanksgiving at the time, and it didn’t become an annual event. For the next two centuries, days of thanksgiving were declared now and then by colonies, states and occasionally presidents. George Washington proclaimed one for November 26, 1789, but there was no fixed national holiday.
The woman who campaigned for it
Much of the credit for a national Thanksgiving goes to Sarah Josepha Hale, the editor of a popular women’s magazine and the author of the nursery rhyme “Mary Had a Little Lamb”. For years she wrote editorials and letters to politicians, including several presidents, urging a single national day of thanks. Lincoln’s 1863 proclamation came after she wrote to him that September.
How the 1941 compromise works
The fourth-Thursday rule was a compromise between tradition and business. In most years, November has four Thursdays and the last Thursday and the fourth Thursday are the same day. Only in years when November has five Thursdays, roughly two years in every seven, does the rule make a difference. In those years, Thanksgiving falls a week before the old last-Thursday date, giving stores an extra week of holiday shopping.

Why the date still matters
The date shapes more than dinner plans. Black Friday, the day after Thanksgiving, is one of the busiest shopping days of the year, and Cyber Monday follows. Airlines and highways see some of their heaviest traffic of the year in the days around the holiday. A late Thanksgiving, like this year’s, squeezes the time between the holiday and Christmas, which is why retailers often start their promotions earlier in years like 2026.
What we think
The story of the fourth-Thursday rule is a reminder that even the most traditional holidays are shaped by politics and business. Roosevelt’s change was driven by retail worries during the Depression, and the backlash showed how strongly people felt about their traditions.
Today the rule is so settled that few people know it was ever controversial. But the tension it resolved, between custom and commerce, is still visible every year in how early holiday shopping season starts.
