How do I? Hour by Hour Occurrences between a Date Range?

Hi Guys,

I have an Excel that I need help with. These dates represent the number of email submissions I got on my website. I'm trying to find out how to see what hours of the day are most popular.

a) I need Excel to give me an hourly breakdown of submissions.
b) I would also like to be able to enter a date range, so that I can enter say "Between November and December".
c) If I can also enter a specific day to see breakdowns for that day only, such as Tuesday's, that would be great.

Attached is an Excel. Any help is appreciated!

For example:
Date Start:
Date End:

Hourly breakdown:
12am to 1am: Submissions
1am to 2am: Submissions
2am to 3am: Submissions
etc.

This is an example of how Column A looks in my Excel.
