Why? I had a rewrite of some core logic the last day before Christmas that I didn'td deploy, as it wasn't time critical to get out and I didn't want to be disturbed during holidays. Today it was perfect to deploy, as I can watch it the whole week if needed.
Well, I think it probably depends on where you work. At my work, people just took 2-3 weeks of time off. It takes a moment to get your head back in the game.
