i used "loose on precision" improperly.
What i meant is, defining fixed ranges (lets say of 30 days) would possibly lead sometimes  to group into the same month, one or two days of another month. 
suppose i start on the 31 jan, setting 30 days as my range to get montlhy stats.
31 jan + 30 would yield 1 or 2 march!
