Finding the number of business days between two dates

Hi, Friends! I am in search of a formula that will tell me the number of business days (Mon-Fri) between two dates.
Column examples below. I am working on a project where I am trying to determine the amount of transit days on UPS Shipments. Thank you in advance for any assistance you can provide!
