Give thanks for whatever you have to be thankful for. If you feel like taking the long view, you can read more about the history of the holiday over at the National Archives website:
On October 3, 1789, President George Washington issued a proclamation naming Thursday, November 26, 1789 as an official holiday of “sincere and humble thanks.” The nation then celebrated its first Thanksgiving under its new Constitution. On October 3, 1863, President Lincoln made the traditional Thanksgiving celebration a nationwide holiday to be commemorated each year on the fourth Thursday of November….
In 1939 President Franklin D. Roosevelt moved the holiday to the third Thursday of November to lengthen the Christmas shopping season and boost the economy still recovering from the Depression. This move, which set off a national debate, was reversed in 1941 when Congress passed and President Roosevelt approved a joint house resolution establishing, by law, the fourth Thursday in November as Thanksgiving Day.
Our friends at NARA even serve up a little poetry for the occasion:
“Thanksgiving, like Ambassadors,
Cabinet officers and others
Smeared with political ointment,
Depends for its existence on
Presidential appointment.”
