October 3, 1789 was the date on which first U.S. President George Washington [February 22, 1732-December 14, 1799] proclaimed a national day of Thanksgiving. He identified that day as November 26th. The holiday continued to be observed, but not on a national level. Its observance tended to be in New England. But the date varied widely, from sometime in October to sometime in January.
Canada's Thanksgiving was first celebrated as a national holiday in 1879, but it was not until 1957 that the Canadian Parliament officially declared the second Monday in October as Thanksgiving Day. This date was chosen to align with the harvest season, reflecting the holiday's roots in giving thanks for a bountiful harvest. Since then, it has been recognized as a separate holiday distinct from the American Thanksgiving.
In the United States, "first Thanksgiving" refers to the the pilgrims and Indians' feast to celebrate a bountiful harvest in 1621. That was 390 years ago from the year 2011. As a national holiday, President Abraham Lincoln proclaimed Thanksgiving a national holiday in 1863. In 2011, that was 148 years ago.
Thanksgiving Day in 2012 is Thursday, November 22nd.
Technically Washington did however it did not become a federal holiday with a set date until Lincoln.
George Washington declared Thanksgiving a national holiday in 1789. However, the Continental Congress (president John Hanson) made the first actual national proclamation on March 16, 1776. The following year, a national day of prayer and thanksgiving was observed on December 16, 1777. The date of Thursday, November 26, 1789 was the date used by Washington, following the precedent of Thursday, November 28, 1782. The annual observance was established by Abraham Lincoln in 1863, and observed each year since then.
Several Presidents, including George Washington, made one-time Thanksgiving holidays. . Although the demand for making it a regular national holiday came in from various quarters, but of little impact. In 1827, Mrs. Sarah Joseph Hale began lobbying. several Presidents for the proclamation of Thanksgiving as a national holiday. It didn't see success until 1863 when Abraham Lincoln finally made it a national holiday with his 1863 Thanksgiving Proclamation. Several Presidents, including George Washington, made one-time Thanksgiving holidays. .
According to the web site http://gonewengland.about.com/od/thanksgivingfacts/ Abraham Lincoln made Thanksgiving a national holiday in 1863. It was the last Thursday in November. Franklin D Roosevelt changed it to the fourth Thursday in 1941. Also, quoting from the web site http://www.calendarmine.com/Holidays/American_Thanksgiving.asp "In 1879 the Canadian Parliament made Thanksgiving a national holiday. It was originally placed on November 6th. In 1957 the government established the holiday on its present date the second Monday of October."
Thanksgiving as a holiday has roots in ancient harvest festivals and religious traditions, but the specific holiday celebrated in the United States traces back to the early 17th century. The first Thanksgiving in the United States is commonly associated with the Pilgrims in 1621, who held a feast to give thanks for their first successful harvest in the New World. However, Thanksgiving did not become an official national holiday until President Abraham Lincoln proclaimed it as such in 1863 during the Civil War.
The Continental Congress proclaimed a Thanksgiving holiday (December 18) in 1777, and Washington proclaimed a Thanksgiving day (Nov. 26th) in 1789. Adams did likewise in 1798 and 1799. Jefferson did not proclaim any such holiday, believing it to be an impermissible conflation of church and state. Madison proclaimed holidays in 1814 and 1815. From 1816 to 1863, there was no federal Thanksgiving, but by the end of that period, most states had established the holiday. Thanksgiving was established annually by presidential proclamation (frequently expressed as a "recommendation" by the president) from 1863 until 1941, when Congress established it as a recurring national holiday. Lincoln's proclamation in 1863 is generally regarded as establishing the national holiday, but it really only proclaimed it for that year. It did, however, establish a precedent followed by his successors, including Andrew Johnson (though in 1865, the holiday occurred in December). In the 1930's, FDR attempted to move the date back one week to enlarge the holiday shopping period, but Congress set the date, and firmly established the holiday, in 1941. Presidents continue to proclaim it, though the proclamation is now superfluous.
While dating to Pilgrim times, Thanksgiving was not formally made a standard Holiday until F.D.R. ( Franklin Delano Roosevelt) codified the date of observance at the fourth Thursday in November in I believe l939. It was always a thursday and in November, but exact date was not fixed until standards-oriented FDR did the, err, Dime turn.
