Hi, @Touris Jade
Thank you for posting in Microsoft Q&A forum.
Configure maintenance windows with an effective date, a start and end time, and a recurrence pattern. The maximum duration of a window has to be less than 24 hours. The console doesn't allow a single maintenance window longer than 24 hours.
So, if you want to allow maintenance from Saturday to Sunday, you may need to create two maintenance windows for each day.
