Yeah for sure - we're a restaurant group and we operate on a
4-4-5 calendar so our "months" always start on a Monday and end on a Sunday. So when analyzing the data, we need to be able to do period over period and year over year comparisons based on the 4-4-5 calendar instead of the Gregorian calendar. I can go into more detail if needed, but broadly the need is just to be able to do comparisons based on and have date pickers that are aware of that calendar.
