WASHINGTON (AP) President Donald Trump has issued a proclamation designating Thursday as a day for the United States to celebrate victory in World War II as countries in Europe already do.

Cities from London to Moscow are holding parades, flyovers and memorials this week as the world observes Thursday’s 80th anniversary of Victory in Europe Day, when Nazi Germany surrendered to Allied forces, including the U.S.

Here’s what to know about Trump’s plans:

What is Trump doing and why?

The Republican president is designating specific days for the U.S. to celebrate being on the winning side in World War I and World War II. He complained in recent social media posts that Americans don’t spend enough time celebrating those achievements, which he said wouldn’t have been possible without the U.S.

“Many of our allies and friends are celebrating May 8th as Victory Day, but we did more than any other Country, by far, in producing a victorious result on World War II. I am hereby renaming May 8th as Victory Day for World War II and November 11th as Victory Day for World War I,” he said last week on social media. “We won both Wars, nobody was close to us in terms of strength, bravery, or military brilliance, but we never celebrate anything That’s because we don’t have leaders anymore, that know how to do so! We are going to start celebrating our victories again!”

Can Trump rename an existing federal holiday?

No. Nov. 11 is already Veterans Day, a federal holiday in the U.S., and only Congress can create, rename or take it back. That could explain why Trump backed away from his “renaming” plan and said he’d instead be “declaring” national holidays instead.

“We won two World Wars, but we never took credit for it Everyone else does! All over the World, the Allies are celebrating the Victory we had in World War II. The only Country that doesn’t celebrate is the United States of America, and the Victory was only accomplished because of us,” he wrote Monday on social media. “Without the United States, the War would have been won by other Countries, and what a different World it would be. Therefore, I am hereby declaring a National Holiday in celebration of the Victories of World War I, where the Armistice was signed on November 11, 1918, and World War II, where the Victory date was May 8, 1945.”

He signed a proclamation on Wednesday that designates May 8, 2025, as a “day in celebration of Victory Day for World War II.” He’s expected to issue a similar proclamation for World War I later this year.

Is Thursday a day off from work?

No, Thursday is not a federal holiday and therefore not a day off from work. Only Congress can create federal holidays, and Trump has complained that there already are too many of them.

What does he envision will happen around the U.S. on these days?

It’s unclear. Trump didn’t say what he envisions happening, and the proclamation didn’t include any details. But he said during an unrelated appearance Wednesday in the Oval Office that he noticed France and other countries were “all getting ready for Victory Day.”

“We don’t celebrate it and I think that’s a great disservice,” Trump said.

What happens in other countries?

On major anniversaries like this year’s 80th, Britain celebrates VE Day with parades, airplane flyovers and memorials. The British royal family traditionally watches the airplanes pass overhead from a balcony at Buckingham Palace.

Russia celebrates on Friday, and its Victory Day parades are a massive show of its armed forces, with thousands of troops, scores of heavy equipment rolling across Red Square and flyovers involving dozens of warplanes. Military parades, fireworks and other festivities are held in cities across the country.

What have veterans groups said about Trump’s plans?

Rob Couture, director of public affairs for the Veterans of Foreign Wars, said they are encouraged by any steps that “bring attention to the service of veterans from that time.”

Just over 66,100 of the 16.4 million Americans who served in World War II were alive as of 2024.
