Count Detentions by Month
I need to count how many detentions were assigned in 'October' for 'Behavior'.
=COUNTIFS(A2:A8, ">=2023-10-01", A2:A8, "<=2023-10-31", C2:C8, "Behavior") How it works: The COUNTIFS function is perfect for counting rows that meet multiple criteria simultaneously. In this formula: - `A2:A8, ">=2023-10-01"`: This is the first criterion, counting dates in the range A2:A8 that are on or after October 1, 2023. - `A2:A8, "<=2023-10-31"`: This is the second criterion, counting dates in the range A2:A8 that are on or before October 31, 2023. Together with the first criterion, this effectively filters for all dates within the month of October. - `C2:C8, "Behavior"`: This is the third criterion, counting entries in the range C2:C8 that exactly match the text 'Behavior'. COUNTIFS will only count a row if *all* specified criteria are true for that particular row, providing an accurate count of detentions for 'Behavior' in 'October'.

Step-by-Step Guide
Identify the columns containing the 'Date' and 'Reason' for detentions in your data (e.g., Column A for Date, Column C for Reason).
Determine the exact start and end dates for the target month (e.g., October 1, 2023, to October 31, 2023).
In an empty cell where you want the result, enter the COUNTIFS formula: `=COUNTIFS(A2:A8, ">=2023-10-01", A2:A8, "<=2023-10-31", C2:C8, "Behavior")`.
Press Enter to execute the formula and display the total count of detentions matching both criteria.
