Where do people feel the extra day should fall? While Monday or Friday is convenient, I can definitely see a point to making it Wednesday, so you can re-charge and be more productive for the second half of the week; in a normal 5 day week, I definitely see tiredness creeping in by Thursday and Friday.
I've been doing it on Monday and it works well. I just take the days off as unpaid days in the leave system so I can request a different day whenever I want or when Monday is a public holiday.

You probably agree a lot with CGP Grey on this video[1]
I really liked when Cloudera did "unplug days" which basically threw in an extra day off every 3 weeks and a double extra off every 3 months, but it was a Friday so there was always the temptation to drive out somewhere or go do something for 3 days.
If it had been Wednesdays, we'd have just slept and relaxed instead.
