Assuming that A2 contains the day of interest (true date value formatted
as "dd"), and B2 contains the month of interest (true date value
formatted as "mmm"), try the following formula which needs to be
confirmed with CONTROL+SHIFT+ENTER...

=INDEX(C4:AO4,MATCH(MAX(INDEX(C5:AO436,MATCH(1,IF( DAY(A5:A436)=DAY(A2),IF
(MONTH(B5:B436)=MONTH(B2),1)),0),0)),INDEX(C5:AO43 6,MATCH(1,IF(DAY(A5:A43
6)=DAY(A2),IF(MONTH(B5:B436)=MONTH(B2),1)),0),0),0 ))

If, however, A2 contains the day of interest, such as 1, 2, 3, etc., and
B2 contains the month of interest, such as Jan, Feb, Mar, etc., try the
following instead...

=INDEX(C4:AO4,MATCH(MAX(INDEX(C5:AO436,MATCH(1,IF( DAY(A5:A436)=A2,IF(TEXT
(B5:B436,"mmm")=B2,1)),0),0)),INDEX(C5:AO436,MATCH (1,IF(DAY(A5:A436)=A2,I
F(TEXT(B5:B436,"mmm")=B2,1)),0),0),0))

Hope this helps!

Hi All,

I have numerous subsets of data listed by Day: 1st - 31st & Month: Jan - Dec.

Is it possible to provide a single Formula to reference a large group of data
containing some miscellaneous rows that should not be reflected in the data
returned. I would like a flexible Formula to explicitly reference specific
Day and Month to find the Maximum value for that specific Day (1st, 2nd, 10th
etc) & Month (criteria will vary) and retrieve its corresponding Numeric
Label from Row "4" Column "C" : "AO"

I may want to find the Numeric Label that has the maximum value for 1st Mar,
2nd Mar, 5 Mar; or 31 Feb, 31 Mar, 31 Dec.

Col "A" = Day, Col "B" = Month, Col "C" - "AO" = Data - Numeric Values

Col "A" Col "B" Col "C" - "AO"
01 Jan
01 Feb
01 Mar
etc
01 Dec

Misc
02 Jan
02 Feb
02 Mar
etc
02 Dec

31 Jan

31 Mar
etc
etc
31 Dec


Numeric Labels = Row4 Col "C" - "AO"
Data = Row5:Row438 Col "C" - "AO" - Numeric Values
Day = Row5:Row438 Col "A" - Full Date formatted with Custom Day Format "dd":
1 - 31
Month = Row5:Row438 Col "B" - Full Date formatted with Custom Month Format
"mmm": Jan - Dec.

Sample Data Layout:
Row4 Day Month 1 2 3 4 5 6
Row5 01 Jan 101 102 123 143 136 128
Row6 01 Feb 120 130 103 87 143 130
