Counting Dates in a Range
I seek help to find a formula to do the following:
I have a range (P2:AB659) that is populated with dates entered 1/16/06 format and displayed as 6-Jan format. I need to count the number of cells containing any date in January, any date in February, etc. TIA, Matt |

Counting Dates in a Range
=SUMPRODUCT(--(MONTH(P2:AB659)=1)
change the 1 to the month number you want to count (ie. Jan=1, Feb=2, Mar=3, etc.) "Matt7102" wrote: I seek help to find a formula to do the following: I have a range (P2:AB659) that is populated with dates entered 1/16/06 format and displayed as 6-Jan format.

Counting Dates in a Range
What is the purpose/meaning of the double dash (--) in this formula?

Counting Dates in a Range
It turns an array of logical terms into 1's and 0's. This way they can be
summed (TRUE/FALSE is ignored when summing). Example: {TRUE,TRUE,FALSE,TRUE}-{1,1,0,1} NOTE: The formula is missing a close parenthesis and should be =SUMPRODUCT(--(MONTH(P2:AB659)=1)) "Bean123r" wrote: What is the purpose/meaning of the double dash (--) in this formula?

Counting Dates in a Range
Thanks for the help, and the short tutorial on explaining the formula
function... however, using a smaller dataset to test, the formula does not return the correct result for January. Works fine for all other months. When I add a date in the range other than January to the test dataset, (or delete an existing) all is well for the month altered. January is just NOT working...any ideas?

Counting Dates in a Range
I have no idea why it wouldn't be working. I made a small list to test that
worked fine. Can you show the list, formulas, and results? Is it giving an error, or the wrong value? What value does the formula produce? What value should it be?

Counting Dates in a Range
Well, I cannot attach the data set, so here is an example: With only a
single column of the range populated: P 2) 1-Jan =SUMPRODUCT(--(MONTH($P$2:$Y$14)=1)) 3) 1-Feb =SUMPRODUCT(--(MONTH($P$2:$Y$14)=2)) 4) 1-Mar =SUMPRODUCT(--(MONTH($P$2:$Y$14)=3)) Etc thru 1-Dec, formula contnues as well. Jan returns 119, all others return 1. If I change 1-Jan to 1-Jun, June formula result changes to 2, and January changes to 118. If I change all 12 to 1-Jan, January result is 130, all other results are zero. If I then clear contents, Jan result is 130, all other results are zero.

Counting Dates in a Range
I just figured out that the cell range is 130 cells, and entering any date
reduces the <blank cell count by one- Jan formula is counting blank cells perhaps? "Sloth" wrote: I have no idea why it wouldn't be working. I made a small list to test that worked fine.

Good problem solving, I didn't realise you had blank cells. Try these
formulas. =SUMPRODUCT(--(MONTH(range)=1),1-(ISBLANK(range))) or =SUMPRODUCT(--(MONTH(range)=1),--(ISNUMBER(range))) "Matt7102" wrote: I just figured out that the cell range is 130 cells, and entering any date reduces the <blank cell count by one- Jan formula is counting blank cells perhaps?

Thanks for the assistance, it now works without error. Hope I can pass along
similar help someday! Matt "Sloth" wrote: Good problem solving, I didn't realise you had blank cells.
