Syntax

expression. EffectiveDateAdd( ** Date, ** Duration )

expression An expression that returns a StartDriver object.

Parameters

NameRequired/OptionalData TypeDescription
DateRequiredVariantArbitrary date and time, for example, "7/10/2010" or "7/10/2010 2:00:00 PM".
DurationRequiredVariantDuration to add, for example, "3d" or "2w".

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.

You can 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.
