I'd like to convert dates to weeks of month, but I'd like the weeks to be counted back to front, kind of. So if there are 5 weeks in a month, I'd like the last 7 days to be week 5, last 8 to 14 days to be week 4 and so on. The first week may or may not have 7 days.
Would love to hear your advice.
(day_in_month - current_day) DIV 7
