How availabilities are used: We only use your availabilities for the next week to find your suggestions.
Changing the calendar range: This does not change availabilities you have already entered, so if you entered availabilities outside of the range you have set, they will still be used to find suggestions. Hint: If you don't want that, change the range from 12am to 12am and clear out availabilities for the times you are unavailable and set your range again.
