Remarks
The EffectiveDateAdd property uses the effective calendar for manually scheduled tasks, which allows tasks to start and finish on non-working times. The property and arguments have no effect on actual task dates.
Use the EffectiveDateSubtract, EffectiveDateAdd, and EffectiveDateDifference properties to calculate start and finish dates for manually scheduled tasks.
To calculate a date for an automatically scheduled task, where you can also specify the calendar, use the DateAdd method.
Example
The following statement returns the value "7/9/2009 5:00:00 PM", which is six days after the specified date.
Debug.Print ActiveProject.Tasks(3).StartDriver.EffectiveDateAdd("7/2/2009", "6d")
