Choose an event type

Choose the default appearance, schedule, and reminders for an event.

Choose an event type

An event type sets how a new event looks, whether it uses times or whole days, and which reminders it starts with. Birthday, Subscription, and Habit events also get their own editor on any calendar. You can change any of these on the event afterward. Changing a subscription or birthday to another type removes its price or birth year, and When asks first.

TypeWhat it’s for
EventGeneral appointments and other timed events.
MeetingCalls, meetings, and reviews.
FlightAir travel, with flight details and separate departure and arrival times.
HotelAccommodation stays. Starts as all-day. A stay you add with Add hotel or the right-click menu lasts one night.
BirthdayA person's birthday, every year on the same day.
Payment / BillBills and renewals. Starts as all-day, and you mark each one paid.
SubscriptionA service you pay for on a schedule, with its price, renewal, and any free trial. You mark each charge paid.
HabitSomething you do on a routine, such as every day or on weekdays. You check each one off and keep a run.
ReminderA marker at a start time, with no duration. You mark each one done.

Reminder type and reminders

The Reminder type controls how an event is drawn. It does not decide whether you get an alert. Any type can send a notification: set one in the event’s Notify field.

Appearance

An event's own theme takes priority over its type's default. The general Event type starts with a neutral slate theme, including on Main. Main's teal thumbnail identifies Main; events in that view keep their own themes.

Filled gives an event a solid background. Subtle uses a lighter tint. To change one event, open its Theme picker and turn Filled on or off.

Flights, hotels, meetings, birthdays, payments, subscriptions, and habits show their type's icon: a plane, a bed, people, a cake, money for payments and subscriptions, and a target for habits. To give one event its own icon, open its Theme picker, choose Icon, and pick one, or type to search for it. The icons you picked last are listed under Recent, below the full set. Remove icon hides the icon, the type's included. The icon shows at the start of the event's title. A period takes an icon the same way, from its Color picker.

To change the defaults for a type, or to create your own type, see Customize event types.
