Oh dear this has been here for over 6 years ... no luck getting this done.

That's the key thing that I need now.

Yes! In Calendar view, I'd really like to only see my working hours, not have to scroll from 1am, and for the 'add time' dropdown to start at that as well, again not in the early hours of the morning! So much repetitive scrolling, or changing the minutes to 00 instead of :15, which ClickUp seems to default to when you just use return to enter.

From support ticket: Can I get my time view to only show 7am to 10,pm
