So that that period would show regardless of what day within the
period I ran the report

This is done on an MS Access form as follows:

Using unbound text-boxes on the MS Access form, add the following code
to the two Text-boxes:
StartDate = Date()-Choose(Weekday(Date()),11,12,13,7,8,9,10)
EndDate = Date()-Choose(Weekday(Date()),5,6,7,1,2,3,4)

And the form text would be something like:
FrmText = "Period: "&StartDate&" Thru "&EndDate

How can I add this to a Microsoft Word 2000 Header?

Any help greatly appreciated.

Thanks,

You can create two custom document properties (StartDate and EndDate), which
you can add and modify programmatically. Then, in your header, you can use
fields to display the correct dates.

<<< Period: { DOCPROPERTY StartDate } thru { DOCPROPERTY EndDate } >>>
