Using Shazam's ul reference, I found that a week can be as short as 1 day. So, the European calendar can have more than one 53 week year in the four year cycle. Strange by true.

A week is a week wherever you are. What may be different is how you define where week 1 starts, whiuch is where the ISO week number definition is much tighter than MS's.

But BD wanted a WEEKNUM replacement, as found in Excel, using Monday as the start of the week. That is exactly what I gave him.
