At film festivals the normal calendar fast fades into irrelevancy. Days of the week matter little compared to the screening schedule.
The same is not true for the rest of the world outside the film bubble, as I found at the subway. Completely unaware it was Sunday, I arrived early in the morning to find the station locked. This put the first film of the day in doubt. Thankfully someone did eventually open the doors and a train turned up 25 minutes later. It meant a close-run thing, but a little bit of sprinting meant I only missed the first ten minutes of Sami Blood.
