How do I change the schedule of what days my ads appear on Google adwords?

The instructions on Google's help page are not helpful and are not correct. There is no EDIT button next to ad scheduling. There is only a question mark that tells you about ad scheduling when you click on it and it tells you how to do it but the EDIT option is not there like it says on the help page. Google also says you can call or contact them via email but the email contact is greyed out and unable to be used and the business hours are closed. There is no 24 hour tech support. UGH!
