"Nuit debout" - "Up All Night", "Standing Night" and/or "Rise up at night" is quite complicated to define, thus I won't do this. I would only suggest that it is a movement that - also - gather the listeners of a French broadcast that doesn't exist any more: "Là bas si j'y suis" - "there if I am" or "go away to see if I am" - it is difficult to translate again. 100 jours - days make me think of Napoléon, but it could be just a coincidence (...). https://nuitdebout.fr/
