I have sickness data, and I want to know how many different colleagues were sick each month. My data includes duplicate values for employee ID as there have been multiple occasions throughout the year that they have been off. I don't want to use a pivot table. Below is an example of my data.

I want to know how many different employees were off in Oct 2021. So unique employee numbers (emp1, emp2 etc.) that are "2021" & "Oct". Thank you.

Emp12021Jan
Emp22019Feb
Emp32021Oct
Emp12021Oct
Emp12021Oct
Emp22021Apr
Emp22020Nov
Emp32021Oct
Emp12020Oct
