What day is Thanksgiving in 2021? Why does the day change every year?
Certain holiday calendar dates in the U.S. appear set in stone.
New Year's Day falls on Jan. 1 and Christmas Day is Dec. 25.
Although we know that Thanksgiving Day is in November and we celebrate on Thursday every year, many still wonder what day Thanksgiving is each year.
The date has been far from set in stone since Abraham Lincoln began the holiday near the end of the Civil War.
So here is what we know about Thanksgiving Day, from when it's celebrated this year to the changing history of the day to be thankful, eat turkey, and be thankful.
When is Thanksgiving 2021?
Thanksgiving falls on Thursday, Nov. 25 this year.
Is there anything consistent about Thanksgiving?
The holiday is always observed on the fourth Thursday in November.
According to information from The Old Farmer's Almanac, Abraham Lincoln was the first person who decided to have Thanksgiving on a particular day, not a date.
When did Thanksgiving Day start?
Lincoln called on Americans to observe the last Thursday of November "as a day of Thanksgiving and Praise" after the Battle of Gettysburg in 1863.
Franklin D. Roosevelt tried to change it
Franklin D. Roosevelt moved Thanksgiving to the third Thursday of November by proclamation as the country was coming out of the Great Depression with hopes that an extra week of holiday shopping would help the economy.
But not everybody liked the idea.
According to The Center for Legislative Archives, 16 of 48 states at the time declined to accept the change, so Congress officially set the fourth Thursday of November as Thanksgiving across the country in 1941.
