When I was reading various things about all the holidays in France in May I recalled that 25+ years ago I wrote the following, then added another para in 2009 and again today:
Aide memoire a propos des fetes:
On the 14 Juillet, restaurants are open if they usually are on that day of the week, the Louvre and selected other museums are, street market to 13H00 - only big magasins, etc closed.
On Nov 11, lunch is a tough go for restaurants - do Brasseries or Bistrot du Dome, etc.
At XMas & New Year's it's pretty much the same as 14 July, XMas eve there's a nifty Xmas eve mass on TV (who wants to sweat with the masses at Notre Dame?) Lots of stuff is open Xmas Day but New Year's Day things are pretty dead
Remember that June has June 8th - WWII end, June 29th - Ascension Day etc.; one holiday almost every week. May Day limited food opportunities.
I added:
Holidays 2008-9
The week between Christmas and New Years one needs to telephone to reserve.
New Year’s Day, except for brasseries, almost nothing was open but Lao Lane Xang 2.
Today (Ascension Day 2010) I noted this:
2010
All the restaurants I called were open, but Monoprix and Franprix closed early and every museum, place owned by non-French folk and many French places (my rich tailor, for instance) were open.
