Hello all! I'm trying find the correct formula to deliver a counted value for the amount of time that has passed since the last time a desired value was shown. For instance, today is 2/11/2021 and I'm trying to figure out how many days have past since the last time "3" was realized. 20 would be the correct amount of days that the formula should solve for (2/11/2021 through 1/23/2021). Anyone have a simple formula to accomplish this?
