The year is also wrong in the sales reports by week, but I'm not sure how to fix the formatting string there to work right.
(For example, filtering from 12/27/2015 to 01/02/2016 shows "week 53 of 2015", but 01/03/2016 to 01/09/2016 is actually returning two rows for me, one is "week 53 of 2016" (??) and the other is "week 01 of 2016")
