The Date1 through Date10 fields are custom fields that store any task, resource, or assignment date information you want.
There are several categories of Date1-10 fields.
Data Type Date (date field: A type of field whose content is a date. Examples include the Baseline Start and Early Finish fields.)
Date1-10 (task fields)
Date1-10 (resource fields)
Entry Type Calculated or entered (calculated or entered field: A field in which the value is determined by Project based on information in other fields. Information that you enter in the field yourself overrides calculated values.)
Best Uses Add one or more custom date fields to a resource sheet to maintain additional date information on your resources. Examples include hire date, birthday, or start date on the project.
Example You want to add birthdays to your resource information. You add the Date1 field to the Resource Sheet view, and rename it "Birthday." Then you enter the birthdays for all resources in this field.
Remarks Any date you enter in a custom Date1 through Date10 field does not affect Project calculations. If no date is entered, the field contains "NA."
You can create custom value lists, formulas, and graphical indicators for any of the custom date fields. You can also create custom attributes or rename the custom date field, in the Custom Fields dialog box. Specifying a formula causes the field to become read-only.
You can copy the custom fields you create, along with their custom attributes, to other project files, in the Organizer dialog box.
