How to skip a day of the week

I'm not sure if that's what you mean but it's possible to exclude the hidden time from the event duration when moving events using drag and drop:

Hi Dan, sorry didn't explain myself well. I want to be able to hide certain days of the week from the scheduler. For example when setting showNonBusiness to false this remove Saturdays & Sundays from the calender, I would like to do this for other days of the week

In that case you can either use onIncludeTimeCell which can hide some of the generated time columns (https://doc.daypilot.org/scheduler/hiding-time-columns/) or you can build your own timeline by defining individual cells (https://doc.daypilot.org/scheduler/timeline/).

Just note that if onIncludeTimeCell handler is defined the showNonBusiness value is ignored (no columns will be hidden by default).
