Find last day of month depending on criteria

[Jeff Jensen]

Range A1:JA1 has all our work days for the year (holidays and weekends are
excluded).

In P32 I want to enter the number of a month (i.e. 1 = Jan, 2 = Feb, etc.)
and have a formula in Q32 that looks in A1:JA1 and returns the largest date
for the month I entered in P32.

Thank you,

Jeff

Try this formula in cell Q32:

=MAX((A1:JA1)*(MONTH(A1:JA1)=P32))

Note: This is an array formula that has to be confirmed by
CTRL+SHIFT+ENTER rather than just ENTER.

Hope this helps / Lars-Åke

q32: =LOOKUP(2,1/(MONTH(A1:JA1)=P32),A1:JA1)

Try this...

Assuming the dates are for the year 2010.

=LOOKUP(DATE(2010,P32+1,0),A1:AJ1)

Format as Date

Thanks T. Valko,
I gave it a try but for some reason this is only working month 1 & 2 but it
doesn't for 3 - 12.
Thanks again,
Jeff

 

[Jeff Jensen]

Thanks Ron, works like a charm!
Thanks again,
Jeff

 

[Jeff Jensen]

Thanks Lars,
I gave it a try but I get a #VALUE! error. I did enter it as an array.
Thanks,
Jeff

 

[T. Valko]

Hmmm...

I assume the dates are in ascending order?

Works just fine for me.

Oh, well!

Thanks Ron, works like a charm!

You're welcome. Glad to help. Thanks for the feedback.

Make sure that you don't have any non valid dates, like 2010-01-35 in
the range A1:AJ1

Lars, I see what the problem was - some last cells had "", I changed that to
0 and it works now.

I hoped your way would work because I thought I could just change MAX to MIN
in order to get the smallest date as well. But that didn't work. Do you know
a way to get the smallest date?

Thank you,
Jeff

 

[Lars-Åke Aspelin]

Try this formula for the smallest date:

=MIN((IF(A1:JA1<1,99999,A1:JA1)*(IF(MONTH(A1:JA1)=P32,1,2))))

Note: This is an array formula that has to be confirmed by
CTRL+SHIFT+ENTER rather than just ENTER.

Hope this helps / Lars-Åke

Thanks Lars,

Works Great!
