# count number of unique dates

Hey Excel Junkies,

I have been trying to find a "sumproduct" solution (or any solution really) for a simple problem. I saw quite a number of postes on here with similar problems but not exactly my problem. Everyone wants to count something or other based on various criteria. I just want to count the number of unique dates for a certain range but cannot make it work.

I can successfully use sumproduct to calculate how many entries for example in Jan 2021 or to calculate how many VVI entries in 2020. Can anyone help me count the number of days an entry was made in a certain time frame ?

NB: This is part of a reporting process with various pivot tables and charts all connected to a slicer where the user can select his reporting month.
So there is a cell for "Report Month" = "Jan 2021"
I use the following formula to count (for example) how many "VVI" entries in the Report Month (RptMth) answer 2 for Mar 2020 based on the beginning date :

=SUMPRODUCT((INT(begin)>=(VALUE(rptMth)))*(INT(begin)<=EOMONTH(rptMth;0))*(type="VVI"))

Or to figure out the pay amount earned (the "pay" column is missing in the data) :

=SUMPRODUCT((INT(begin)>=(VALUE(rptMth)))*(INT(begin)<=EOMONTH(rptMth;0))*pay)

Can someone help me figure out how to count the unique number of days an entry was made?
For Jan 2021 the result should be 3 (4th, 5th and 6th Jan) ;
for March 2020 it's 2 (1st and 2nd Mar) .

Many thank (and a pint to the genius) who figures this out.
Cheers,
RvL

An alternative is Power Query.

Cheers Fluff,
Cheers as well to the others who gave it a stab, but Fluff wins the pint (if ever the pubs open again)!

Fluff, you are a star !!!
I know of "rows" but never really come to grips with it. I've tried working with "unique" but with no great success and "filter" is completely new to me. I was looking for a simple formula and you delivered it. I've applied to my full data base and it works like a charm. Thank you.

Now I am going to try and figure out now how to apply it to the days of the week to see (for example) "how many Mondays" were worked.
I've been able to calculate the volume on "Mondays" (for exemple) but can't seem to count "how many Mondays were worked in a given Report Month".

I have five years of data with approximately 20 to 50 entries per day. My objective is to be able to see in any given "report month" whether there are certain days of the week that have a consistent (or periodical) higher volume. I can use this formula to calculate number of entries on Mondays
=SUMPRODUCT((INT(begin)>=(VALUE(rptMth)))*(INT(begin)<=EOMONTH(rptMth;0))*(WEEKDAY(begin;2)=1))

But what I can't figure out is "in any given month, how many Mondays, Tuesdays, Weds... etc were worked". If I know that, I can use it to calculate the average earned on those days and use this figure for staffing purposes.

Here is more elaborate data to play with.

PS: power query looks like an interesting concept if ever the MAC world gets blessed with it. we are blessed with a no/low virus environment but because of that, we don't get all the icing on the cake (or the cherries).

Haven't figured out a way to combine this, but the helper columns seem to do it.

Dynamic array formulas.

kWeaver,
Your option works but it means too much extra work for a database that is updated numerous times throughout the day. One thing does intrigue me in your formulas though. I've never seen formulas with a "#" sign (at least not in that manner). Please can you help me understand this? Or maybe it's something that only works on a PC?

=UNIQUE(RIGHT(G2#,6))
=COUNTIF(\$G\$2#,H2)
