Why do we celebrate thanksgiving on the fourth thursday of november?

Thanksgiving originally started as a day to give thanks, to fast and pray. A day of thanksgiving could be declared by anyone, for any reason. George Washington was the first to declare a national Thanksgiving Day in America: "Whereas it is the duty of all Nations to acknowledge the providence of Almighty God ... therefore I do recommend and assign Thursday the 26th day of November next to be devoted by the People of these States to the service of that great and glorious Being, who is the beneficent Author of all the good that was, that is, or that will be."

A few of our presidents after him declared a day of thanksgiving for one reason or the other (sometimes not even in fall), but the first president to establish an annual tradition was Abraham "I do therefore invite my fellow citizens in every part of the United States, and also those who are at sea and those who are sojourning in foreign lands, to set apart and observe the last Thursday of November next, as a day of Thanksgiving and Praise to our beneficent Father who dwelleth in the Heavens. " However, it was Franklin D. Roosevelt who really established Thanksgiving as it is today.

From Wikipedia: "Abraham Lincoln's successors as president followed his example of annually declaring the final Thursday in November to be Thanksgiving. But in 1939, President Franklin D. Roosevelt broke with this tradition.

November had five Thursdays that year, and Roosevelt declared the fourth Thursday as Thanksgiving rather than the fifth one. In 1940 and 1941, years in which November had four Thursdays, he declared the third one as Thanksgiving. Although many popular histories state otherwise, he made clear that his plan was to establish it on the next-to-last Thursday in the month instead of the last one.

With the country still in the midst of The Great Depression, Roosevelt thought an earlier Thanksgiving would give merchants a longer period to sell goods before Christmas.
