Lame Duck Day is celebrated on February 06, 2023. A lame duck is an elected official who is approaching the end of his or her tenure, especially one whose successor has already been elected. The phrase lame duck was coined in the 18th century at the London Stock Exchange, to refer to a stockbroker who defaulted on his debts.
Lame Duck officials tend to have less political power, as other elected officials are less inclined to cooperate with them. However, lame ducks are also in the peculiar position of not facing the consequences of their actions in a subsequent election, giving them greater freedom to issue unpopular decisions or appointments.
