Why is Thanksgiving on the fourth Thursday? Because since 1941, federal law has fixed the holiday on the fourth Thursday of every November. But that rule is younger than most people think — and for more than seventy years before it, Thanksgiving fell on a different Thursday.

If you have ever wondered why is Thanksgiving on the fourth Thursday instead of a fixed date like Christmas, the answer winds through a Civil War proclamation, a Depression-era president, angry retailers, and a two-year national argument nicknamed “Franksgiving.” The date on your calendar is the result of all of it — and understanding why is Thanksgiving on the fourth Thursday starts with the one thing most people get wrong: the holiday has never been a fixed date. It is a rule holiday, and the rule has been rewritten more than once.

Key Facts

• Thanksgiving falls on the fourth Thursday of November every year — the calendar date moves between November 22 and 28.
• Abraham Lincoln’s 1863 proclamation set the last Thursday of November as the holiday; that rule held from 1864 through 1938.
• In 1939 and 1940, President Franklin D. Roosevelt moved Thanksgiving a week earlier to lengthen the Christmas shopping season — the era nicknamed “Franksgiving.”
• Congress ended the confusion on December 26, 1941, when a joint resolution (H.J. Res. 41) made the fourth Thursday federal law.
• “Fourth” is not the same as “last” — in Novembers with five Thursdays, the fourth Thursday keeps the holiday a week before the calendar’s end.

The Short Answer: Why Is Thanksgiving on the Fourth Thursday?

Thanksgiving is on the fourth Thursday of November because a joint resolution of Congress, signed by President Franklin D. Roosevelt on December 26, 1941, made it so. The resolution (H.J. Res. 41) designated the fourth Thursday of each November as Thanksgiving Day, a legal federal holiday in the United States.

Before that law, the date was whatever the president’s annual proclamation said it was — and for two straight years, 1939 and 1940, that meant two different Thanksgivings in different states. Congress chose the fourth Thursday as a compromise: it preserved the familiar late-November timing while keeping the date from sliding to November 30 in years when the month has five Thursdays.

The law took effect starting with Thanksgiving 1942, and every president since has simply issued an annual proclamation naming the fourth Thursday — never moving it. States quickly fell in line, and the school calendars, parade schedules, and football traditions we know today were all built on top of that single sentence of legislation.

nd an argument about it.”

Why Thanksgiving Moves Around the Calendar

November always has 30 days, but it can hold either four or five Thursdays depending on where the month starts. When November begins on a Friday, Saturday, or Sunday, there are four Thursdays and the fourth is the last one — falling on the 26th, 27th, or 28th. When the month begins on a Thursday, there are five Thursdays, and the fourth Thursday falls as early as the 22nd. That is why the holiday can land anywhere from November 22 to November 28, and why is Thanksgiving on the fourth Thursday is a question about a rule, not a date.

This rule-based system is not new. Long before any federal law existed, American Thanksgivings were simply declared, year by year, by whoever had the authority to declare them. George Washington’s famous 1789 proclamation named Thursday, November 26, 1789 — which happened to be the last Thursday of that November. After Washington, the practice faded for decades; several presidents issued no Thanksgiving proclamation at all.

Everything changed in 1863. In the middle of the Civil War, Abraham Lincoln issued the proclamation that made Thanksgiving a regularly observed national holiday, setting it on the last Thursday of November that year — November 26, 1863. Lincoln’s successors kept the tradition going, year after year, each president naming the last Thursday of November in his annual proclamation. That “last Thursday” rule held unbroken from 1864 all the way through 1938 — 75 years of stability that made the date feel ancient and unchangeable. Our full history of Thanksgiving traces this era in detail, from colonial harvest feasts through Lincoln’s proclamation.

“For 75 years, Thanksgiving fell on the last Thursday of November by presidential habit — not by law. Habits, it turns out, can be broken.”

The FDR Date Change: 1939–1941 (“Franksgiving”)

The country was still clawing out of the Great Depression in 1939, and American retailers had a problem. November that year had five Thursdays, which meant Thanksgiving — still observed on the last Thursday by tradition — would fall on November 30, the latest possible date. Retailers argued that a Thanksgiving that late would steal a full week from the Christmas shopping season, costing them millions in holiday sales.

President Franklin D. Roosevelt listened. In August 1939, he announced that Thanksgiving would be celebrated on November 23 — the second-to-last Thursday — giving shoppers an extra week. Critics immediately coined the nickname “Franksgiving”, and the backlash was fierce. The country split down the middle: 23 states and the District of Columbia went along with the new November 23 date, 22 states stubbornly observed November 30, and Texas and Colorado threw up their hands and celebrated both.

The confusion was enormous. School calendars were already printed. College football rivalries were scheduled around the traditional date — some games had to be played twice, in spirit if not in fact. Families with relatives in different states found themselves with two Thanksgivings and no clear plan. Calendars printed with one date were wrong in half the country.

Undeterred, Roosevelt moved Thanksgiving again in 1940 — once more to the second-to-last Thursday, November 21. That year the split was even wider: 32 states observed the new date while 16 held to the last Thursday. Two years of national bickering had made one thing clear to everyone: letting the date shift at the president’s whim was not working.

“For two years, America had two Thanksgivings — one by tradition, one by presidential decree — and neither one felt quite right.”

The 1941 Law That Made It Permanent

By late 1941, Congress had seen enough of the annual argument. Lawmakers drafted a joint resolution that would settle the question once and for all — not by presidential proclamation, which any president could change, but by federal law, which would bind every future administration.

The resolution, H.J. Res. 41, designated the fourth Thursday of November as Thanksgiving Day. Congress passed it in December 1941, and President Roosevelt signed it into law on December 26, 1941 — just weeks after the attack on Pearl Harbor had drawn the United States into World War II. Even in the middle of a national emergency, the country wanted its holiday date settled.

The National Archives preserves the records of this moment: its press release on the Thanksgiving date history covers both Roosevelt’s 1939 move and the 1941 joint resolution that fixed the fourth Thursday permanently. The law took effect with Thanksgiving 1942, and the “Franksgiving” era — two Thanksgivings, two dates, one confused nation — was over.

Why the fourth Thursday, and not simply a return to the old “last Thursday”? Congress wanted to preserve what Roosevelt had been trying to do: keep the Christmas shopping season as long as possible. In years with five Thursdays, the fourth Thursday is a full week earlier than the last, and Congress locked in that longer season permanently.

“Congress did not invent Thanksgiving in 1941. It ended an argument about it — and made the argument illegal to restart.”

Why Is Thanksgiving on the Fourth Thursday — Not the Last Thursday?

This is the question people ask when they notice the calendar oddity: in most years, the fourth Thursday of November is the last Thursday of November. The distinction only matters in Novembers that contain five Thursdays — which happens whenever November 1 falls on a Thursday.

Take 2028 and 2029 as examples. In 2028, Thanksgiving falls on November 23 — the fourth Thursday — while the last Thursday would be November 30. In 2029, the fourth Thursday is November 22, but the last Thursday would be November 29. If the old “last Thursday” rule were still in force, Thanksgiving in those years would land a full week later, pushing dangerously close to December.

That week matters for two practical reasons. First, the Christmas shopping season: retailers, then and now, want as many shopping days between Thanksgiving and Christmas as possible, and Congress in 1941 was explicit that this was the point. Second, travel and planning: a consistent rule that never pushes the holiday to November 29 or 30 gives families, schools, and employers a predictable anchor. The fourth Thursday can fall no earlier than November 22 and no later than November 28 — a neat seven-day window that has held steady for more than eighty years.

So when someone asks why is Thanksgiving on the fourth Thursday instead of simply the last one, the honest answer is: because Congress decided that in the years when the two are different, the earlier date serves the country better. The “last Thursday” tradition lasted 75 years. The “fourth Thursday” law has now lasted more than 80 — and unlike the tradition, it cannot be changed by a president’s whim.

Frequently Asked Questions

Is Thanksgiving always on the fourth Thursday?

Yes — it has been since the law took effect in 1942. But it was not always this way: from 1864 through 1938 the holiday fell on the last Thursday of November, and in 1939–1940 President Roosevelt moved it to the second-to-last Thursday, creating the split-date “Franksgiving” era.

What happened in 1939?

November 1939 had five Thursdays, so the traditional last-Thursday Thanksgiving would have fallen on November 30 — the latest possible date. Under pressure from retailers worried about a shortened Christmas shopping season, President Roosevelt proclaimed Thanksgiving for November 23 instead. The country split: some states followed the president, others kept the traditional date.

Why did FDR move Thanksgiving in the first place?

Money and jobs. The country was still recovering from the Great Depression, and retailers argued that an extra week of Christmas shopping would boost sales and employment. Roosevelt agreed and moved the holiday earlier to stretch the season. The move was controversial enough that critics dubbed the early date “Franksgiving.”

Why is Thanksgiving on the fourth Thursday instead of the last Thursday?

Because Congress chose it deliberately in 1941. In years when November has five Thursdays, the fourth Thursday falls a full week earlier than the last one — preserving a longer holiday shopping season and keeping the holiday from landing as late as November 29 or 30. In years with only four Thursdays, the fourth Thursday is the last Thursday, so most years feel no different.

Do other countries celebrate Thanksgiving on a different date?

Yes. Canada celebrates its Thanksgiving on the second Monday in October, with different historical roots tied to the harvest season further north. The American fourth-Thursday rule is unique to the United States. If you want the deeper story behind the holiday’s meaning, our guide to why Thanksgiving is celebrated covers the traditions behind the date.

Whatever Congress decides in the future, whenever someone asks why is Thanksgiving on the fourth Thursday, the answer will always begin with the 1941 compromise.

Could Thanksgiving ever be moved again?

Legally, yes — Congress could pass a new law changing it, since the date is fixed by statute, not the Constitution. Practically, it is extremely unlikely: more than eighty years of school calendars, travel patterns, parade traditions, and football schedules are all built around the fourth Thursday, and no president can change it by proclamation alone.

Conclusion

So the next time someone asks why is Thanksgiving on the fourth Thursday, you have the full story: a Civil War proclamation that set the last Thursday, a Depression-era president who moved it for the sake of Christmas shopping, two years of national confusion, and finally a 1941 law that settled the argument for good. The fourth Thursday is a compromise written into federal law — early enough to give the holidays room to breathe, late enough to feel like the harvest season it celebrates. Set your calendar, plan your travel, and give thanks that you no longer have to celebrate twice.
