Here are Thanksgiving Day Statistics for Peoria & Springfield, IL.
While Thanksgiving had been celebrated unofficially in the United States for many years, it was on October 3, 1863 that President Abraham Lincoln officially declared the last Thursday of November as Thanksgiving Day. In 1941, Congress moved the date to the fourth Thursday of November (effective in 1942), in part to clear confusion caused by a Proclamation issued by President Franklin D. Roosevelt. For a full timeline on the history of Thanksgiving, head over to the Library of Congress. The statistics compiled on this page use the last Thursday of November through 1941, and the fourth Thursday from 1942 to present.
