Date Question

[Guest]

I have an Excel SS that has a summary page that has several count if / sum if
values. Many of which refer to date ranges. today etc.

Is it possible for me to capture all data in a range of the last calander
month ie. if i all dates in October.

Currently i have the formulas written to count details within the last 31
days however i would like to make this a little more correct.

example :
=SUMPRODUCT((whoC="gn") * (typec="email " ) * (whenb<B1) * ( whenb >B2) )

B1 = Now()
B2 = B1 - 31

Any help very much appreciated

Hi
try:
B1:
=DATE(YEAR(NOW()),MONTH(NOW())-1,1)

B2:
=DATE(YEAR(NOW(),MONTH(NOW()),0)

In B1 put the starting date, i.e. 10/1/2004. In B2, manually enter the end
date, 10/31/2004, or use a formula like =DATE(YEAR(B1),MONTH(B1)+1,0) which
will generate the last day of that month, 10/31/2004, for you.

Then the formula is

=SUMPRODUCT((whoC="gn") * (typec="email " ) * (whenb>=B1) * ( whenb<=B2) )

Hi
typo on my side. Try:
=DATE(YEAR(NOW()),MONTH(NOW()),0)

Thanks Frank,

I actually worked it out about 3 minutes after posting my reply.. my fault i
am a novice when it comes to date functions..

I don't suppose there is an easy way to work the same equasion out but for
last calander week ??

Again Thanks

Assuming the calendar week starts on Sunday, this formula starts with the
current date, backs up to the previous Saturday, then backs up another 6 days
to the Sunday before the previous Saturday. If the current date is a Saturday,
it will back up a total of 13 days.

=TODAY()-WEEKDAY(TODAY())-6

The end of that week is that date + 6.
