What were the dates of Thanksgiving Day from 1900 to 2006?
In 1863 Abraham Lincoln gave his Thanksgiving Proclamation, declaring the last Thursday in November a day of thanksgiving. It wasn’t until 1939, that Franklyn D. Roosevelt wanted to lengthen the Christmas shopping Season by moving Thanksgiving to the 4th Thursday in November. Controversy followed, and Congress passed a joint resolution in 1941 decreeing that Thanksgiving should fall on the fourth Thursday of November, where it remains to this day. So knowing that, if you are trying to track the actual dates you will need to go back in your calenders to check the specific date.
