Time array question

Occasional Contributor

Hi ,

I need to look at the course start and end date. Then in a given month I want to find if the course was running. For a given month I want to find how many courses run.

I tries countifs , which was not working well for me.

Hi @Imi_Jay 

 

With the data you sharedI can't reconcile your "manual" counts/totals

Below are courses that have a Start date in 2021 only:

- Columns F-Q are Jan 2021-Dec 2021

- Row 17 is my count of running courses

 

Where's my mistake/misunderstanding?

Hi @Imi_Jay 

 

Please check whether the following solution is helpful:

 

Formula in cell F2 is: =COUNTIFS($B$2:$B$28,"<="&EOMONTH(E2,0),$C$2:$C$28,">="&E2)

 

NOTE

1. Values in range E2:E14 are dates: 1-Jan-2021, 1-Feb-2021,1-Mar-2021 . . . 1-1-2022.

I applied Custom Formatting to make these dates appear as mmm-yyyy.

2. In the above suggested formula, please change cell reference/ranges to suit Your requirement.
3. Please drag the formula down to more rows.
