First lady Melania Trump tried to commemorate National Pearl Harbor Remembrance Day on social media Thursday, but accidentally included the wrong date in her message.
"Today we honor Pearl Harbor Heroes. 11/7/1941," Trump wrote on Twitter, attaching a photo of her and husband President Trump standing in front of a list of fallen military service men and women.
"Thank you to all military for your courage and sacrifice!" she added.
The U.S. naval base at Pearl Harbor, Hawaii, was attacked by Imperial Japanese aircraft on Dec. 7, 1941, not Nov. 7.
President Trump also tweeted his own sentiments to mark the anniversary of the surprise strike that killed 2,403 Americans.
"National Pearl Harbor Remembrance Day - 'A day that will live in infamy!' December 7, 1941," he wrote.
National Pearl Harbor Remembrance Day - “A day that will live in infamy!” December 7, 1941— Donald J. Trump (@realDonaldTrump) December 7, 2017
The famous quote uttered by then-President Franklin D. Roosevelt during his Infamy Address before a joint session of Congress on Dec. 8, 1941, is actually: "A date which will live in infamy."
