Walk into a stationery store in British Columbia and you'll find both options.

Perhaps though that is due to the increasingly globalized world and stationery stores desire to have a lot of varied product from great product makers in Japan, USA and further afield.

I grew up aware that some people considered Sunday the start and others Monday, but didn't seem like there were any real firm rules about it where it mattered. I feel like I saw both being used. I always preferred using Monday as the start of the week.

Edit: Had a quick look at the Vancouver recycling calendar they sent me in the mail: Sunday first.

Yeah, Staples or a high end paper craft store will have both.

But if you go into one of those popup calendar stores, all the calendars will be SMTWTFS.
