I have a Google Sheet that I use to track attendance at an open lab that I run. Each quarter I put together a report where I count the number of people that attended that quarter. If I just use the count function I could include people that only attended the first quarter in the second quarter report or that attended the second in the third.
I want a way to say, "if this person attended between these dates then count them."
For example, in the picture I attached Name 2
only attended during the first quarter so they wouldn't be included in the second quarter count. Name 5
attended during both so they would be included in both counts.
My best idea for putting this into Google Sheets is
=countif(A2:A29,B2:Y2<>0)
or in other words count the names if they attended during the first quarter. Is there any way to do this?
Edit: Here's a link for the spreadsheet:https://docs.google.com/spreadsheets/d/1SwukY3SsjWfYyu2RakED0S0V4kZwRfNN0nVoDsKMN5A/edit?usp=sharing
Doing this manually there should be 38 people that attended during the first quarter and 42 that attended the second.

Here's a sample where I tried to solve the issue in tab "Result"
There's some additionnal columns for each quarter (
A:A, B:B, C:C
) then with some QUERY you can check if there has been an attendance or nah.The formula in
A3
:=index(transpose(query({transpose(INDIRECT(A2))},"Select "&textjoin(",",TRUE,ArrayFormula(if(len($D$3:$D$100),"Max(Col"&ROW($D$2:$D$100)-ROW($D$2)+1&")","")))&"")),,2)
There is a main query with the range
A2
for the first quarter: in this cell you can add the desired range, you can try a formula to automate this. (I.E. filter every date with the desired months ('=MONTH') then take the reference of the cells containing `MAX' and 'MIN' values)The query select the max value of every row (the range has been transposed). You can also use dynamic range for the
LEN
andROW
formulas.Then it just
=TRANSPOSE
the data.=INDEX
is way to pick the second column (first column is fill with names)You can now go to tab
Clean
for a simple=IF
formula checking wether or not attendees where present during quarter/period 1Edit : Credit for 3/4 of the formula
