Holiday/Blackout days in Timeline/Gantt Views

It would be great if we could blackout days that we don’t want our items to be scheduled on. Major holidays and company vacation days so we don’t accidentally schedule something over one of those days.


I encounter this gap in functionality when planning a project that is about to overlap with the upcoming holidays in IL in September

Be able to block holidays as a working days is an important feature


I sencond this we really need this as it’s basic project management requirement!
