I like the calendar view where you're able to get a summary of a particular month. It would also be informative to be able to select between 2 dates. A customized report/view would allow comparative analysis over several dates that are not bound to a particular month. So for instance you want to view a summary for a roadtrip/vacation lasting several days or investigate a particular cold spell over several days and how it impacted your efficiencies, etc.
