A quick terminology guide:

• An appointment is an item you create for yourself.
• A meeting is just like an appointment, except that it includes more than one person.
• An event is an all-day appointment or a note about that date. It can be for you alone, or you can invite people.

You’ll follow very similar steps to create and work with appointments, meetings, and events.
