How can I construct a formula that will relate TODAY to the 1st
Tuesday of each month.

For example as today is 01/12/07, my formula should return 04/12/07,
but if TODAY was 05/12/07, then it should return 01/01/08 etc

Thanks

=IF(AND(A1=A1-MOD(A1-3,7),MONTH(A1-7)<MONTH(A1)),A1,IF(MONTH(A1-MOD(A1-3,7))=MONTH(A1),EOMONTH(A1,0)-MOD(EOMONTH(A1,0)-3,7)+7,A1-MOD(A1-3,7)+7))

You have a minor problem in your formula... it will produce the wrong date
whenever the date in A1 is the first of the month on a Wednesday (try August
1, 2007 for example). This stems from your using the +7 and -4 adjusters.
Normally, the fix would be to use +8 and -5 (at least that would be the fix
in order to find the first such-and-such day in a month); however, I notice
that your original formula and your formula modified as I just mentioned,
both get December 31, 2008 wrong... they report February 3, 2009 instead of
January 5, 2009 as the first Tuesday of the next month (given that December
31st is greater than its own first Tuesday)... I'm not sure off-hand what,
if any, "rule" there is governing when this problem will crop up (mainly
because I didn't look for one).

One other possible problem with your formula, although I am thinking this
may simply be an interpretational problem where the OP wasn't specific as to
what he wanted. If the date is the first of the month and it is a Tuesday,
you formula returns the next month's first Tuesday instead of acknowledging
the date as the first Tuesday of the current month. As I said, this is
probably an interpretational reading as to what the OP means by "next 1st
Tuesday", but I figured I should mention it anyway, just in case.

Rick

Rick, very very astute

Rick, very very astute

Not really... I once proposed a first such-and-such day in a month solution
using the +7/-4 adjustment and found it produced incorrect results when
tested against another solution that used the +8/-5 adjustment... so I am
kind of sensitive to its usage and I notice its use more readily because of
that. However, there may be a problem with the +8/-5 adjustment method also
(see my other post in this thread)... when I get the time to look into it, I
will try and prove or disprove its usage in the simple first such-and-such
situation (I can't be sure it is a general problem with the method or just
one that cropped up because of the additional requirements from the OP's
request).

Rick

(I can't be sure it is a general problem with the method or just

from the OP's request).

The OP being you, of course :-)

Rick

The OP still didn't say what to do if today is the 1st Tuesday of the month.

Good pickup! You're correct, and I should know better as I've made that same
mistake before!

In any event, modified:

=IF(A1-DAY(A1)+8-WEEKDAY(A1-DAY(A1)-2)A1,A1-DAY(
A1)+8-WEEKDAY(A1-DAY(A1)-2),DATE(YEAR(A1),MONTH(
A1+1),8)-WEEKDAY(DATE(YEAR(A1),MONTH(A1+1),6)))

Oh, and I interpreted the OP's request for the "Next" Tuesday to mean that if
TODAY is a Tuesday, the "Next" Tuesday would necessarily occur in the future.

OK, the major flaw in my formula was that I was not computing the next month
correctly. As a consequence it would fail if the "starting date" was "late in
the month". I've corrected that in this version, as well as changed the
adjustments.

=IF(A1-DAY(A1)+8-WEEKDAY(A1-DAY(A1)-2)A1,A1-DAY(

I gotta hand it to you "date" guys! I spotted the flaw in your formula
around 3 hours ago. I've been trying to come up with a working formula ever
since.

Here's what I came up with:
A1: (a date)
A2: (the Weekday to return....1=Sun, 2=Mon, 3=Tue, 4=Wed, 5=Thu, 6=Fri,
7=Sat)

This formula returns the NEXT first Tuesday of the month
(the final "3" in the formula is the weekday to find):
=MIN(CEILING(A1+1,(A1-DAY(A1)+{1;32})-DAY(A1-DAY(A1)+{1;32})+7
-MOD(6+WEEKDAY((A1-DAY(A1)+{1;32})-DAY(A1-DAY(A1)+{1;32})+1)-A2,7)))

It was not clear from the OP's postings what he wanted to have happen in
that case, so it is open to interpretation. However, with that said, the fix
for the formula I posted is extremely simple... one would just change the
greater than symbol () to a greater than or equal symbol (=).

(given that December 31st is greater than its own first Tuesday)...
I'm
not sure off-hand what, if any, "rule" there is governing when this
problem will crop up (mainly because I didn't look for one).

One other possible problem with your formula, although I am thinking
this
may simply be an interpretational problem where the OP wasn't specific
as
to
what he wanted. If the date is the first of the month and it is a
Tuesday,
you formula returns the next month's first Tuesday instead of
acknowledging
the date as the first Tuesday of the current month. As I said, this is
probably an interpretational reading as to what the OP means by "next
1st
Tuesday", but I figured I should mention it anyway, just in case.

Rick

OK, the major flaw in my formula was that I was not computing the next
month
correctly. As a consequence it would fail if the "starting date" was
"late in
the month". I've corrected that in this version, as well as changed
the
adjustments.

=IF(A1-DAY(A1)+8-WEEKDAY(A1-DAY(A1)-2)A1,A1-DAY(
A1)+8-WEEKDAY(A1-DAY(A1)-2),A1-DAY(A1)+40-DAY(A1-DAY(
A1)+32)-WEEKDAY(A1-DAY(A1)+30-DAY(A1-DAY(A1)+32)))

Many thanks Guys for your detailed responses, although I didn't know
how to compute it, wasn't aware it might have been that complicated,
so your efforts are really appreciated.

Just to clarify, I'm using the date as a notice of when a Report is
due to be returned. The bases is that its due on "the 1st Tuesday of
each month", but specifically its due by 12pm on the 1st Tuesday, so
if the user opened up the file at 2:00pm on the 1st Tuesday, he/she
should see the following months 1st Tuesday date. If the user opened
the file up at 10:00am on the 1st Tuesday, he/she should see the
current days date pop up

Are you sure you want to do it that way? What if the report the person is
checking on is really due "today" and the person is just checking about it
late (in other words, after 12 noon)? You are going to give that person an
extra month just because they are late in checking when to return it.
Perhaps you should consider adding a Date Borrowed or Date Checked Out (or
whatever heading makes sense for your application) column so that the
formula can see if the the current first Tuesday is the correct first
Tuesday to report.

By the way, here is the formula I posted, modified to use the 12-noon
breakpoint...

=IF(NOW()TODAY()-DAY(TODAY())+8-WEEKDAY(TODAY()-DAY(TODAY())+5)+TIME(12,0,0),DATE(YEAR(TODAY()),1+ MONTH(TODAY()),1)-DAY(DATE(YEAR(TODAY()),1+MONTH(TODAY()),1))+8-WEEKDAY(DATE(YEAR(TODAY()),1+MONTH(TODAY()),1)-DAY(DATE(YEAR(TODAY()),1+MONTH(TODAY()),1))+5),TOD AY()-DAY(TODAY())+8-WEEKDAY(TODAY()-DAY(TODAY())+5))

Notice that it now uses the actual current date-time rather than refer to a
cell's content. That should match more closely what you asked for
originally.

If that happens Rick, I'll just give them the sack.. Its only a simple
guide for the user, I guess I just change A1 to =TODAY()+(720/1440) ??

Ignore my post with all those TODAY() function calls; that would probably
not be an efficient formula. Instead, I would probably do it this way... put
=TODAY() in A1 and use this formula...

=IF(NOW()A1-DAY(A1)+8-WEEKDAY(A1-DAY(A1)+5)+TIME(12,0,0),DATE(YEAR(A1),1+MONTH(A1), 1)-DAY(DATE(YEAR(A1),1+MONTH(A1),1))+8-WEEKDAY(DATE(YEAR(A1),1+MONTH(A1),1)-DAY(DATE(YEAR(A1),1+MONTH(A1),1))+5),A1-DAY(A1)+8-WEEKDAY(A1-DAY(A1)+5))

Notice that NOW() is checked against A1's content modified by the 12-hour
offset to noon. You could use the 0.5 (what you wrote as 720/1440) instead
of TIME(12,0,0) as I showed, but I like the clarity of the TIME function
call myself.

Thanks Rick

Then you could use a simpler formula. For the date/time in A3,

=INT(A3-WEEKDAY(A3-1.5,2)+7*MATCH(TRUE,DAY(A3-WEEKDAY(A3-1.5,2)
+7*{1;2;3;4;5}+0.5)<8,0)+0.5)+0.5

Elegant.

Guys a twist on my OP, how could I return a similar value, but this
time the "last" Thursday of each month?

This just tests if the date is the one you are looking for, so you can use it with Conditional formatting.

=AND(DAY(A2)<8,MOD(A2,7)=3)

And this one returns the next 1st Tuesday of the month date.

=A2+MATCH(1,N(MOD(A2+ROW($1:$35),7)=3)*(DAY(A2+ROW ($1:$35))<8),0)

Array entered.

A nice, compact formula for the next 1st Tuesday... excellent!. However, if
the first of the month is a 1st Tuesday, it returns the next month's 1st
Tuesday... is there a way to stop that? Actually, more important to the
thread is the recently clarified requirement from the OP that on such first
of the month, 1st Tuesday dates, if the time is before noon, the current
date should be returned and if after noon, the next month 1st Tuesday should
be returned instead. Your formula appears to "choke" when a time component
is added to the date. Can your formula be adjusted to accommodate this
requirement?

Based on Harlan's approach for 1st Tuesday then with date and time in A3 this
formula will give you the "next" last Thursday at noon, changeover point
again being on the last Thursday at noon

=INT(A3-WEEKDAY(A3+2.5)+0.5+7*MATCH(TRUE,DAY(A3-WEEKDAY(A3+2.5)+7.5+7*{1,2,3,4,5})<8,0))+0.5

Question... do you really need the +0.5 at the very end of your formula?
Putting it in adjust the returned date to 12 noon; I think the OP simply
needed the date of the applicable 1st Tuesday and not the date plus a time
offset.

Rick

Okay, I played around with your formula a little bit and came up with this
slight modification...

=INT(H19+MATCH(1,(MOD(ROUND(H19,0)+ROW($1:$35)-1,7)=3)*(DAY(ROUND(H19,0)+ROW($1:$35)-1)<8),0)-0.5)

It consistently produces the same results as Harlan's formula; that is, it
properly moves a first of the that is also a 1st Tuesday to the next month's
1st Tuesday if the time portion of the date is after 12 noon. At this point
in time, I have no idea if this can be tightened up any or not. I would note
that this formula and Harlan's are about the same length (I removed the N
function call from you formula and the +0.5 from the end of Harlan's as they
seemed unnecessary for the question the OP asked); however, the above
modification to your formula has 8 function calls whereas Harlan's formula
has only 5... on the face of it, I would guess that means Harlan's version
is slightly more efficient; however that could be mitigated some (or made
worse, I guess) by the difference in the way array calls are implemented
between them.

It doesn't hurt. If the formula were numerically formatted just to
show the date, it'll display the correct date. If it were formatted to
show date and time, it'll show the correct time. The 4 or so CPU
cycles needed to add a constant power of 2 to the INT() call's result
shouldn't cause undue performance drag.

Last Thursday of the month for the date in cell A3 is given by

=A3-WEEKDAY(A3-4,2)+7*(MATCH(TRUE,DAY(A3-WEEKDAY(A3-4,2)
+7*{2;3;4;5;6})<8,0))

Make similar adjustments as in my previous response to use noon as the
cutoff time on that day.

Note: A3-WEEKDAY(A3-n,2) is the previous n_th day of the week before
the date in cell A3, where n_th is in the same sense as WEEKDAY(.,2),
i.e., 1=Monday, 2=Tuesday, etc. Then note that there are at most 5 of
any given weekday in any given month.
