When we have a new market to add or have to remove an existing market, we create a new project for that market. Within that project, we will have multiple custom tasks for different aspects of the market, and as part of that task is a custom date field for "Speed to Market"
So for example:
Project A:
Task 1 - Speed to Market = 10/22/2025
Task 2 - Speed to Market = 10/1/2025
Task 3 - Speed to Market = 10/15/2025
I am trying to create a formula that will take the earliest speed to market (by project) and get the date difference with the latest speed to market. So in this case, for project A the difference would be 10/22 - 10/1 = 21 days.
Any help on figuring out this formula would be great. I know there is already an issue with excluding weekends/holidays but want to start trying to work on this portion before resorting to external reporting methods.
