I've been able to break down the data by day to see if we met either for that day, but having trouble figuring out how to put that into weeks.

Want the brutal-but-effective way? Don't even try to parse the date. Do a table lookup instead. Precalculate a mapping of date string to week number, and load it into a hash a program startup. Then you can map the date string to a week number quickly, without having to break the date into pieces and do math on them. In the grand scheme of things, there aren't that many dates in a year, so space isn't really an issue.

Just make sure that the your definition of 'week' matches that the SLA, particularly when a week crosses a year boundary. Occassionally the legal definition gets odd.
