Creating a formula

Sample sheet attached.

I would like to create a formula which counts the number of times , the name in column F turns up on in Column B on the matching date and time

So far example I would like count the number of times the name Jason turns up in Column F between 01/01/2024 1700 and 02/02/2024 0800
and so on for every name down the list in Column F

Thank you !
