I am looking to Count the number of Employees that are working for each
Hour of the Day.

My Database will show an entry for each Employee per Day, with Start
Time and End Time (Col B = date; Col C = Start Time for that Day; Col D
= End Time for that Day). This Database table is dynamic

On my Presentation Sheet of have the Business date appearing in Col D
to J and the Time split in hours in Col A, thus 9:00am; 10:00 etc etc

I'm looking for some formula that will achieve a Count of the number of
employees for each Day that are "clocked in" for each Hour. The formula
would then have to Reference Col C and D in my Database.

I have Dynamic Named Ranges set for the Database but not sure how I
count for a Particular Hour as this has to take into consideration if
'the employee has a Clock out time later than the hour I am looking to
Count for'

Any assistance would be great
