Intro: I calculate the Saturday out of a weeknumber and a year. From that given date I can calculate the Sunday of the given weeknumber.
I use those two values in a CF to calculate the range of dates from Sunday to Saturday for the given weeknumber (and year). All of this is working fine and perfect. But now I need as basis a week that starts at Friday 16h00..... Wow, my week doesn't go from Sunday 0h00 to Saturday 24h00, but from Friday 16h00 to the next week Friday 16h00 (or 15.59.59 if you want) Any idea how to tell FileMaker that in the context of the above calculation and CF ? More than thank you... JW
