This question already has an answer here:
(Widdershins is a Scottish term which means "contrary to the sun's course".)
It's quite simple: part of the worldbuilding is that certain people are forced to travel around the globe perpetually eastwards, albeit at quite a slow rate - let's say about 20 miles a day on average, varying. I figured this would give a complete circumnavigation of the globe in about one calendar year. Obviously, (for part of the journey) this would result in a slow foreshortening of the days while they move eastward.
Anyway, my question is what effects might that have on human behaviour, psychology, circadian rhythms etc?
It seems to me a slow enough transit that we'd adjust quite easily, but I'm wondering if there's anything else you might need to consider?
The mechanism for transit will be vehicular, so there could easily be a technical solution to any issues - I just need to know about them.
Many thanks, PH
