Configurable intervals (or special hours)
On a side note, probably the "working hours" use case is highlighting a missing feature that is present, for instance on vue-cal (https://antoniandre.github.io/vue-cal/#ex--special-hours) Special hours aren't events as such but reference areas in the timeline that are shown in the background. Just saying.

Yeah could be great for indicating when you're (un)available.
Reference to an idea for how to implement this, as so-called background events: https://github.com/schedule-x/schedule-x/issues/405#issuecomment-2094591561
