How bookings work — Booked by the night, on the scheduler

Cottages, rooms, boats and hire cars are booked in days, not hours. Give the view a start date and an end date that carry no time of day, and it becomes a chart with a row per unit and a column per day. The end date is the day the unit comes free again, not the last night. A cottage booked the 1st to the 8th is available on the 8th, and the next guest's bar starts in that same column. That is what every hotel means by check-out, and reading it the other way would report most of a busy month as double-booked.
