Scheduler — the appointment book — Six ways to look at it
Resource is the one most schedulers open on: one day, one column per staff member, room or chair — including people with nothing booked, because an empty column is the one you want to fill. Day is the same day in a single column. Week puts the seven days side by side. Month answers “how busy is this week” rather than “what time”, so it shows counts and the first few bookings; clicking a day opens it. Agenda is the next 30 days as a list, and the one that reads best on a phone.
Stays is for anything booked by the night rather than by the hour — a cottage, a room, a boat, a hire car. It is a chart with a row per unit and a column per day, and each booking is a bar across the days it occupies. A scheduler switches to it by itself when its dates carry no time of day and it knows when each booking ends.
The hour grid always shows a working day even when nothing is booked, and grows to fit anything outside it — an early appointment widens the window rather than being hidden off the top.
