I've spoken to Airbnb about this before, it's a massive issue for hosts. During summer my calendar is set to a 1 week minimum requirement on a fri to fri basis. However when i look at the calendar on the Airbnb website, as if i was a guest looking to book dates, it shows only the Friday of every week that is available, and every other day as unavailable. Yet if I click on the Friday the following days up to the next Friday then show up as available. It's stupid. I told Airbnb this on numerous occasions but no one could give me an answer as to why the calendar does this (no surprise there!!). I argued that it could potentially lead to potential guests looking elsewhere as they see my calendar as unavailable apart from the Friday's, it's a nightmare.
