Only used one tool for the data prep here (not including the select at the end). The calcs are a bit messy, but the result works in the end.

solution attached.. I reviewed the solution and noticed it has a lot of manual code in it. Do we think it is more efficient to have manual code in a formula or more tiles? Is one considered best practice?

Not the most elegant solution since I used 4 DateTime tools, but hey, it works!
