DayPilotScheduler component, set businessbeginshour and businessendshour - why is 23 showing?

Simply adding ShowNonBusiness="false" should be enough.

And a demo here:

Let me know if it didn't help.

"Simply adding ShowNonBusiness="false" should be enough. " isn't enough...

I'll look into the two other programming options..

Dan and Team,

I've resolved the problem by adding in more code to specifically look for start hour of 23 and end hour of 0 - when that occurrence is met, hide the time column for 23.
