How far in advance do you wish customers to make bookings with you? You may want to limit this to a short time like 1 month, so you can plan your life outside of your business, or you may want to maximize bookings and set no limitations to how far in advance customers can book with you.
To set how far in the future customers can book with you:
Click on Booking tools and select Online booking settings
Find the option to Block availability after
Use the drop-down menu to select an option, whether that be in days, months, or no limit.
