Whether it’s because of a synced calendar or a canceled reservation, there are various reasons why nights on your calendar may be blocked.
Your availability settings: Your calendar will automatically block nights to fit your listing’s availability settings such as availability window, minimum nights, preparation time, advance notice, and restricted check-in dates. You can find the specific reason for why a date is blocked when you tap or click on blocked nights. You can open these blocked nights by overriding settings for select nights only or edit settings for all nights.
Short-term stay restriction: Airbnb may block your calendar if your listing is located in a city that doesn’t allow reservations shorter than certain days.
