Provide a built-in method to do custom calendars
I am a Financial Analyst that works for a large corporation that has a 52/53 week calendar. All of the cool features like Time grouping and PREVIOUSMONTH for PowerPivot or Excel seems to need some work around to use the tools... For example, our months always end on a Sunday which means that our quarters are always 13 weeks. The functionality built into the app would always add or subtract a few days because everything is based on calendar.

Was there any need to mention that you are a financial analyst working for a large corporation? It seems like you're just trying to show off your importance to provoke a sense of urgency.
