This is interesting. I never anticipated so many people would think of it as a circle. I mentally picture a calendar we had in my kindergarten classroom. It was a regular (USian, with the start of the week on Sunday) wall calendar, but all the pages had been cut out and hung in a line with January at the ceiling and December just above the floor.
Relatedly, I've recently put a line in my .bashrc to display the ISO week number (date +%V) in addition to the traditional date. Knowing that we're in week 42 of the year somehow helps me get a better sense time passing than knowing it is the third Wednesday in October. In general I think the world lives in weeks rather than months and it's a little unfortunate that our date system obscures this.
