was the day that President Franklin D Roosevelt signed a bill that formerly established
that every next to last Thursday in November would be celebrated as Thanksgiving
Day. Before this it was generally the last Thursday in November.
earliest Thanksgiving Day celebration was probably in 1621. William Bradford,
governor of Plymouth Plantation, invited local Indians to join the settlers in
a three day festival to celebrate the bounty of the season.
the late 19th century, Abraham Lincoln declared that Thanksgiving should fall
on the last Thursday of November. It was then that Thanksgiving became a national
holiday throughout the USA.
