Excel 2007

This is driving me nuts, primarily because I know that I've done this
before, but I just can't seem to zero in on the solution today, and I
haven't been able to find it in my other files. I need a formula that does
the following two things:

1) If the current day is a Friday, put the current date
2) In all other cases put the date of the *next* Friday

I seem to remember that this requires a combination of the DATE(), DAY(),
NOW(), and WEEKDAY() functions. I also seem to remember that the solution
*may* include use of the MOD() function. Anyone have a way to do this?

=A1+7-WEEKDAY(A1+1)

I found a formula on the Internet that works.

=TODAY()-WEEKDAY(TODAY())+IF(WEEKDAY(TODAY())6,13,6)

Anyone have a better way of doing this?

The general formula Ron posted is much better (he assumed the date you
wanted to reference was in A1 whereas you are interested in today's date
only); here is his formula restructured for the specific way you want to use
it...

=TODAY()+7-WEEKDAY(TODAY()+1)

As Rick wrote, merely substitute TODAY() for A1 in the formula I previously
posted.

=A1+7-WEEKDAY(A1+1)

or put TODAY() in A1 or some other cell to be referenced.

The formula I posted can be generalized to:

=A1+7-WEEKDAY(A1+7-DOW)

where DOW is Day Of Week and 1=Sun,2=Mon...6=Fri,7=Sun

Obviously, that should have ended ...6=Fri, 7=Sat
--ron

Wow! My recollection on how to do that was way off! ;-)

Thanks for the help. I've added your formula to my file and it works
perfectly.

Hi. You may be thinking of this, where the '6 represents your "Friday"

=A1+MOD(6-WEEKDAY(A1),7)

If the question was about Thursday, change '6 to '5.

Combining MOD(n,7) with WEEKDAY, which also does a MOD(n,7) function seemed
illogical to me, even though it works.

In other words,

=MOD(6-WEEKDAY(A1),7)

and

=7-WEEKDAY(A1-6)

both return the same values

(And, if you are using the 1900 date system), so does:

=6-MOD(A1,7)

--ron

Ah! Yep, I think it was something like that. I seem to remember that the
solution I came up with a couple of years ago worked by using MOD, and then
figuring out the day based on the remainder returned. So it was probably
something very much along the lines of what you've suggested.

Either your date is way off by accident or you did it on purpose to stay at
the top of the list. By definition, I routinely delete those. Too bad if you
had a legitimate question.

I had a formula that worked for six of the seven days of the week. It
failed on Saturdays so I reset my system clock to May 9 so that I could test
my formula. It looks like I forgot to reset to the correct date before
posting the message. My apologies.

Hi Tom,

I can definitely help you with this! Here's a formula that should do the trick:

Let me break it down for you:

1. WEEKDAY(TODAY()) returns a number representing the day of the week (1 for Sunday, 2 for Monday, etc.) for today's date.
2. IF(WEEKDAY(TODAY())=6,TODAY(),...) checks if today is Friday (since Friday is the 6th day of the week). If it is, it returns today's date using the TODAY() function.
3. If today is not Friday, the formula moves on to the next part: TODAY()+7-WEEKDAY(TODAY(),2). This adds 7 days to today's date (to get to the next Friday) and then subtracts the number of days between today and Friday (using the optional second argument of the WEEKDAY() function, which specifies the day of the week to use as the first day of the week - in this case, Monday).

So, if today is Friday, the formula returns today's date. If today is any other day of the week, the formula returns the date of the next Friday.

I hope that helps! Let me know if you have any questions or if there's anything else I can do for you.
