Not a good title. It would suggest too brief a moment in time. It would also suggest a day of great joy. Far from it. Although the more pedestrian parts of this film are of Palin walking through cemeteries looking for stones with the date of death being 11th November 1918, and pointing out, rather patronisingly, that this doesn't necessarily mean that they were shot on this day. There are also some interesting parts:
Hitler's reaction to the German surrender as a private.
The suppression of a report into the ridiculous attack after surrender, allowing American commanders to receive honours for the pointless, condescending, self-aggrandizing loss of life of thousands of soldiers, resulting from their orders of stupid hubris. It's what politics is all about.
If you want to feel sick to the bottom of your stomach to see the very worst aspects of human behaviour, a must see.
