You can set how far in advance you want your calendar to appear on your booking page. It ranges from anywhere from 'now' to '6 months'.
We recommend keeping it at a maximum of 3 months to allow us to detect your Google/Outlook calendar events (synchronizations do not work for more than 3 months in advance).
You can change these settings under the menu item "Availability" -> "Set Availability" when scrolling down to "Date range". Here you can customize your booking window.
