Seemed more an accepted and practical practice of trying to beat the traffic to their weekend mountain/coastal cabins. They are just shaving off an hour or two off their normal leaving time, and is somewhat seasonal and weather dependant as well.

I was just always amazed how quiet the office was on Friday afternoons during the years when I went back to working in Norway. Great for me as I got lots done during those hours. Or perhaps not great as I did not have a cabin to travel to...

Anecdotally having a Friday beer o'clock in the office does not work in Norway. Partly as they frown upon drinking at work... and also there is no-one left in the office.
