Closures and time off are for anything that does not repeat every week: a public holiday, a week away, a training afternoon, an unexpected day off. Go to Availability in the admin and press Add closure or time off.
For a pattern that repeats, change the weekly hours instead. A day your business is always closed goes in Settings → Hours (see Set your opening hours). A regular lunch break is a gap in that person's working hours (see Add your team and their hours).
Whole business or one person
Applies to sets the scope: Whole business or One person. Closing the business hides every time in that range from your booking site, and whole days closed in the next 30 days show there under Upcoming closures. Time off for one person leaves everyone else bookable.
Leave All day on to close one day or a run of dates. Turn it off to close part of a single day, so "closing at 14:00 this Friday" is a closure too, not a permanent hours change.
The same page works the other way round: open on a day you're normally closed, or put someone on for a one-off shift.
Bookings already in the range
If bookings already exist inside the range you are closing, Rantevo will not cancel them automatically.
Once you save, it lists exactly which bookings are affected and asks what to do with each: Cancel, Reschedule or Keep. If you cancel one, the customer is emailed automatically. Reschedule opens that booking in a new tab so you can move it. Close the list without choosing and every booking stays as it was.
Only owners and managers get that list. When a colleague adds their own time off, their bookings in that range stay put for you to move or cancel from Bookings.
So add closures before the dates fill up. The earlier you enter one, the fewer bookings you will have to deal with by hand.
After a closure ends
There's nothing to undo. Availability returns by itself once the date range is past, and you can delete a closure at any time to reopen those dates immediately.
