Set fixed start and end dates for your bookings
If you only want to take bookings from a set date or during a fixed period of time you can set start and end dates. This will stop anyone from being able to make bookings outside of these dates. Find the setting in the Times & availability section, then Availability:
You can add a start date, end date, or both.
Make sure your fixed end date falls after your fixed start date
Make sure your minimum booking notice falls within this fixed start/end date window
Make sure your maximum booking notice falls within this fixed start/end date window
