It would be great to have a way to set up a time frame in which to view a group calendar. For example, in the 2014 SURF group, it would be nice for the calendar to default to the May - August 2014 period.  As time goes on, we now see a blank calendar in 2015, but there were many events back in 2014 that we may want to review without having to remember what dates to type in to scroll back to the correct time.
