Important appointments, Leave, birthdays, claim due dates, etc look so much more comprehensive on a calendar than in a list box.

Or what about a scheduler/planner to view appointments or tasks, and edit them? 

Enter Hot Dates. you'll be able to view date related information in a calendar (drilling down to month, week and\or day views) in a few minutes.

Print your calendar straight to a printer, or edit date related information from the calendar using Drag and Drop, Cut/Copy/Paste or a traditional update.
