Lead created Out of hours - email trigger

Hi all Slight smile

Quick question on the best practice to manage out of hour Leads

We have a number of Leads coming from website into CRM out of working hours and we would like to automate a separate response based on this

Mon - Fri 9am - 7pm

Sat - 10am - 4pm

Sunday - Closed

- Created a "Business Centre" with the days and hours criteria but not sure how to use this with BPM

- Calculated fields for "Day of the week" - need support on how I extract "Hour of the day" from Date created

Any feedback so signposting to the right place would be much appreciated Slight smile
