Just wondering if there is a start and end date of the current view (scheduler._mode).
For example, I use AJAX to get me evets, so I look at the scheduler._date and calculate the end of the year if in year view or end of the month if in year view.
It would be good to have two other properties (if not already present):
scheduler._viewDateStart
scheduler._viewDateEnd
At the moment I use calculations (functions) to obtain this information.
Just an idea
