This dialog allows the task list to be filtered by dates.  Date filtering can be applied based on completion, creation, modification, or due date.

When filtering with one of the "Before" or "After" date filters, the specified starting or ending dates are not inclusive.  For example, consider the case of filtering by Due Dates Before 10/30/2005.  If a task has a due date of 10/30/2005 it will not be included in the task list, but if it had a due date of 10/29/2005, it would be included.

When filtering with one of the "Between" date filters the starting and ending dates are inclusive.

When filtering with the "Due Upcoming" filter option, a value of 1 day shows only tasks due today.  A value of 2 days shows tasks due today or tomorrow, etc...
