The Project Start Date is used to align the start of the project. This value can be entered with either a DATEw. (that is, 01MAY2004) or a DATETIMEw. (that is, 01MAY2004:08:30:00) format. Alternatively, by clicking the button, you can access an Edit Date window to specify the desired value.
A project finish date can also be specified. If neither of these dates is specified, the project start date is automatically set to the current date upon initial scheduling.
