I have an Excel sheet with dates in the rows. A given month should be used only once in a row. How can I filter out, if there are two dates in the same row from the same month?
For example I have the following array, and I would like to have as a result, that there is a match in this row (2012-03).
2012-03-04 2012-02-05 2012-04-06 2012-03-07 2012-10-08 2012-11-09 2012-12-10
I have tried to combine aggregate and match functions, but I cannot find out how to do it properly.
One of my codes, of course it gave an error:
=aggregate(9,6,(MATCH("*"&LEFT(A8,7)&"*","*"&LEFT(b8,7)&"*",0), MATCH("*"&LEFT(b8,7)&"*","*"&LEFT(c8,7)&"*",0)))
Ok, now I have tried another way, and I could get a solution, but with a code which is like a km long...I have first created a new dataset, cutting down the days by using: =""&LEFT(A8,7)&""
Then I have compared all the cells in a given row of my new dataset. Could someone help me how to shorten the exact( ) parts? The aim is to compare all.

Thank you in advance.
I am not sure if there is a better way, but this is how I'd tackle the problem based on my Excel knowledge:
Add data of dates above in cells A1-G1
On row below date add formulas for dates: A2=DATE(A1) ..... G2=DATE(G1)
At the end of the original row of dates add the numbers 1 thru 12:
using formula cell H1=1, I1=H1+1 ..... S1=R1+1
After the months on row 2:H2=COUNTIF($A2:$G2,H1) ..... S2=COUNTIF($A2:$G2,S1)Counting frequency for each of the 12 months
T2=MAX(H2:S2)
Then select on cell T2being more than 1.
Here it is as a Google sheet (you can download it and open in Excel if you want)
Maybe this will help. Assume that the range of dates is in $A$1:$G$1. Also assume that the entries are numerical dates; if they are instead text you can handle this by using the DATEVALUE function. Then we can get the years and months of the range with:
{=YEAR($A$1:$G$1)}
{=MONTH($A$1:$G$1))
This and all other formulas must be entered as array formulas (CrtlShiftEnter).
We next convert back to a date, but use 1 for the day, so that all dates get shifted to the first day of the month (this means that any dates from the same month are shifted to the same date):
{=DATE(YEARS,MONTHS,1)}
We can produce an NxN comparison of the shifted dates by:
{=TRANSPOSE(SHIFTED_DATES)=SHIFTED_DATES}
We can count the number of True's in this array by:
{=SUM(--(ARRAY))}
If there we no dates from the same month we'd expect this to sum to N because this method compare each date to itself as well as the other dates. The causes the N elements on the main diagonal of this array to be True. If any dates are in the same month off-diagonal elements will also be True. So to detect if there are dates from the same month we make the comparison:
{=SUM(--(ARRAY)) > N}
or more generally:
{=SUM(--(ARRAY)) > COUNT($A$1:$G$1)}
Rolling all of these up into one formula:
=IF(SUM(--(TRANSPOSE(DATE(YEAR($A$1:$G$1),MONTH($A$1:$G$1),1))=DATE(YEAR($A$1:$G$1),MONTH($A$1:$G$1),1)))>COUNT(DATE(YEAR($A$1:$G$1),MONTH($A$1:$G$1),1)),"same month","ok")
If your dates are in a range other than $A$1:$G$1 then make the appropriate substitutions.
Hope that helps.
I have the opposite query for this question:
Excel - Lookup to return multiple values in between date range
The solution is given for the above query in the following link also:
https://www.get-digital-help.com/2009/12/13/formula-for-matching-a-date-within-a-date-range-in-excel/
But my query is that for multiple date ranges, how do I find the total bookings of a single date.
I wish to build a calendar which will allow me to work out how many booking I have for a certain day. All the bookings are for 1 or more items and I want the total items which will be there on a single day, across a date calendar range.
On the calendar on the right side, I wish to add the total items which will be staying over during that specified date.
So, in the example, on the 26th December, a total of 6 items will be there. And for 5th December there is only 1, while for 1st December there are no items.
Would like to have these numbers in the calendar on the right.
I have tried using VLOOKUP, LOOKUP, INDEX and MATCH.
Also, tried the SUMPRODUCT mentioned, but those seem to give a single range and number for that range, but not the multiple values across a date range.
https://chandoo.org/wp/range-lookup-excel/
Formulae I tried are, for the 26th December date are:
=(LOOKUP(H10,((Table1[Date From]):(Table1[Date To])),Table1[Items from]))
=SUMIF(Table1[Item],(LOOKUP(2,1/(Table1[Date From]<=H10)/(Table1[Date To]>=H10))))
=INDEX(Table1[Item from],MATCH(H10,LOOKUP(H10,Table1[[Date From]:[Date To]])))
For Dec 26th (and keeping your original structure)
=SUMIFS(Bookings[[Items]:[Items]],Bookings[[Date From]:[Date From]],"<=" &H10,Bookings[[Date To]:[Date To]],">="&H10)
Note that I used the absolute address structured reference form so you can at least fill/drag across a row, without changing the columns from the table.
If you want to make things even easier, you can replace the H10 reference with a computed reference, but at the cost of using OFFSET which is a volatile function.
=SUMIFS(Bookings[[Items]:[Items]],Bookings[[Date From]:[Date From]],"<=" &OFFSET(H$1,ROW()-2,0),Bookings[[Date To]:[Date To]],">="&OFFSET(H$1,ROW()-2,0))
You might also be able to construct a computed cell reference using the INDEX function, which would be non-volatile.
Updated answer with array formulas
Sorry for not understanding your first request.
You can use the following array formula in a "single cell"
{= SUM( IF( (E2 >=$B$2:$B$8 ) * (E2<=$C$2:$C$8) ; $A$2:$A$8 ; 0 ))}
Where column e contains the target dates, columns a, b and c contain items, from and to.
This formula is expansible and copiable to other cells where e2 will be relatively changed for each target date. This is easily adaptable to your month table. Put the formula below the first date, then expand horizontally and copy/paste to the other rows.
See picture:
Old answer
Create a separate cell with your target date. Suppose $e$1.
Create on e2 this formula: =if( and( $e$1 >= c2 ; $e$1 <= d2 ); a2; 0)
Expand it and sum at the bottom.
Sorry for my formulas in Portuguese in the image (se = if ; e = and):
