This comment should be moved inside the if and I would only keep "ISO week 1 does not start until the next Monday" (or maybe no comment at all). Waiting for Erlend's opinion on this.

I'm not sure the comment is needed. The code below speaks for itself, IMO. Let's just remove the XXX comment. After all, that is what the PR title says this PR should do.

@erlend-aasland Got it! I've reverted the change

week1monday = firstday - firstweekday
if firstweekday > THURSDAY:
week1monday += 7
