By default, the MaxDate property is 12/31/9999. The MaxDate property indicates the upper limit of the event. In other words, the Start or End properties of the Event can not be greater than the MaxDate property. You can use the MinDate/MaxDate property to limit the area where the event could occur. The Resizable property of the Event indicates whether the user can resize the event at runtime ( start, end or both ). The Movable property of the Event indicates whether the user can move the event at runtime. You can use the MinDate/MaxDate property of the Calendar object to limit the dates that the calendar can show.
