What day is Thanksgiving in 2021? Why does the day change every year?

There are certain holiday calendar dates in the U.S. that appear set in stone.

New Year's Day falls on Jan. 1 and Christmas Day is Dec. 25.

Why?

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.

For many people, turkey is the prize on Thanksgiving.

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 the 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.
