I think that both Loren and Teresa give good examples of how you might achieve what you want
My thoughts are much simpler - If you know exatly when the start and end of your "blackout perio are",just use a list of NORUN statements
NORUN 25th-31st day of October 2021
NORUN 1st-5th day of November 2021
etc.
I am sure there are many other ways you can achieve your end-results - that's the beauty of ESP
