In Settings > Calendar > Calendar View there is an option “Show range”. This has the default of “Work Day Hours” with options to set specific ranges such as “12 Hours”.
My work day hours are currently set to 8:00 - 17:00. I want to change my work day hours to show 8:00 - 20:00 and I cannot find where to do this.
I am using version 10 in Windows 10. How do I do this?
Oh no, it’s true. I am going blind!
Many thanks 
Actually I wasn’t blind, merely confused. I had changed the end time but nothing had happened on the screen. I now realise that the “Granularity” setting plays a crucial part too.
To see 8:00 to 21:00 on the screen I have to set the start and end time and then set the granularity to 30 mins. With my previous setting of 15 minutes the screen displays 8:00 at the top of the screen but 16:30 at the bottom.
It all makes sense to me now.
