Date manipulation

[Chris]

I need to find a way to write a query that will return the date of the
Friday of four weeks ago. So, if I use today's date (7/30), I should
be returning 7/6 as 4 weeks ago on Friday. Any help is appreciated.

Access has powerful date mathematics functions.

DateAdd() does what it says, adds a number of periods e.g. days,
weeks months, to a date, or substracts them
Weekday() returns a number from 1 to 7, from Sunday to Saturday.

First we need next Friday:
Dateadd("d", 7- weekday(date(), vbSaturday ),date())

Then we subtract 4 or 5 weeks:(not sure if you mean 4 weeks ago
from last or next friday.

DateAdd("ww",-4, Dateadd("d", 7- weekday(date(), vbSaturday
),date()))

Paste that in the field row of the query designer, change the
expr1: to a meaningful name, and test it.
