In France, it happens the 14 of July...
There's a military parade on the Champs Elysées with the French president and this year, Donald Trump, was invited.
This day commemorates the Storming of the Bastille (la prise de la Bastille) in 1789.It was The day of the French révolution. It's now the national day, the Bastille day..
It's of course a public holiday, with huge fireworks, the most famous one from the Eiffel tower
Hope I helped....
