You can set a deadline for guests to cancel or reschedule a confirmed booking.
Specify how many hours before the start time cancellations and rescheduling are accepted. You can set a value from 0 to 720 hours in one-hour increments.
This feature is available on the Basic Plan and above.
For instructions for guests, see Cancel a Booking and Reschedule a Booking.
Difference when no deadline is set
If no deadline is set, guests can cancel or reschedule until the booking's end time.
If a deadline is set, guests can cancel or reschedule until the configured time before the booking's start time.
For a booking from 11:00 to 12:00:
Without a deadline, the guest can cancel or reschedule until 11:59, immediately before the end time.
With the deadline set to 0 hours before, the guest can cancel or reschedule until 10:59, immediately before the start time.

Open Advanced settings for the calendar.
Under Cancellation / reschedule deadline, select Set a cancellation / reschedule deadline.
Enter how many hours before the start time cancellations and rescheduling should close.
You can enter a value from 0 to 720 hours in one-hour increments.
