I'm not sure exactly what you're trying to do, but if you want to see your stats for a certain date (or date range) then you can use the normal
Filters window.
If you mean that you want to see your stats for each day then there is a report in the
Repository which does that.
Splitting a report up based on time gaps between when hands were played is much more difficult. It *might* be possible in a custom report but I can't think how you'd do it just now..
