Increased View Duration

This demo illustrates displaying several days, weeks, months instead of only one on a view. The view’s [intervalCount][0] specifies how many times the default view interval (a day, a week, a month) is repeated on the timetable, and the [startDate][1] defines the date from which to start counting this interval.
