Overview:
This section explains the steps to block a room from the [Dashboard] → [Reservation] → [Booking Calendar].
This feature can be used to set maintenance periods for rooms or temporarily reduce the number of rooms available for sale during a certain period.
You can select rooms individually or select multiple rooms. It is also possible to block all rooms at once.
Details:
What is a block?
Blocking is a function that stops the availability of a specific room on a designated date, preventing reservations from being accepted for that particular room .
Main use cases:
When used for cleaning, inspection, and maintenance.
When sales are stopped due to owner use, etc.
For information on the difference between this and the "Stop Sales" feature in pricing management, please refer to the help page below.
Block display specifications and important points to note
If you set multiple blocks for consecutive dates, by default they will be automatically merged and displayed as a single block .
Example:
June 8 - June 10: Create block "Block-A"
June 10 - June 12: Create block "Block-B"
→ On the calendar, it will appear as a single continuous block.
If you want to display them individually
If you want to display the blocks separately, please refer to the help page below and enable the " Keep blocks separate " setting.
How to create a block
⚠️ You cannot create a block on a date that is already booked.
If you wish to stop sales for a date that has a reservation, please use the "Stop Sales" function on the pricing management page.

Frequently Asked Questions (FAQ)
Q. Can I create a block on dates that already have reservations?
A. No, it is not possible to create a block on dates that already have reservations.
Blocks are used to stop inventory, so they cannot be applied to dates where reservations already exist.
If you want to stop selling dates that already have bookings, please use the “Stop Sell” setting in the Rate Management page.
For more details on the difference between Stop Sell and Block, please refer to:
FAQ: How should I use Block and Stop Sell?
Q. Do blocked dates affect OCC (Occupancy Rate)?
A. It depends on your report settings.
You can configure whether blocked dates are included in the OCC calculation under:
Admin Console → Account Settings → Report Settings → OCC Calculation Rule
For detailed setup instructions, please refer to the following help article:
Q. Why aren't the blocks created in my OTA reflected in the AirHost calendar?
A. Blocks created on the OTA are not imported into AirHost. AirHost is the source of calendar availability, and its calendar is synchronized to each OTA. To ensure your availability is updated correctly, always create blocks in AirHost before synchronizing with your OTA.
