My process consists of once a new item has been created in a list, the list should call back to previous items and update a date field based on business and holidays. The only field I need to change is the date. The remaining can be copied.

The reason for this automation is we have a SP calendar that contains all the same data except the date for each quarter. My goal is create a workflow that populates all data once an item is created. The changing factor is the date based on business days and holidays. I need to skip over Sat and Sun.

I have managed to create this successfully using the Loop action. The problem I have is the time it takes to create each items, 5 mins, up to 30 total. My next approach was a For Each, the issue I have is leveraging a field that changes and can manipulate a variable to change the date. Basically stuck on evaluating the day of the week. Does anyone recommend a different approach or do you think the issue is with a unique identifier to instruct the work flow to evaluate the date?
