# Calendar Events

Read, create and track the events in your users' calendars:

- [Calendars & Events](https://docs.cronofy.com/developers/calendar-and-availability/calendar-events/calendars-events/index.md) covers the basic
operations on calendars and events.

- [Time Zones](https://docs.cronofy.com/developers/calendar-and-availability/calendar-events/time-zones/index.md), [Filtering Events](https://docs.cronofy.com/developers/calendar-and-availability/calendar-events/event-filtering/index.md),
[Editing Events](https://docs.cronofy.com/developers/calendar-and-availability/calendar-events/editing-events/index.md), and
[Out of Office](https://docs.cronofy.com/developers/calendar-and-availability/calendar-events/out-of-office/index.md) go into the detail of
working with those events.

- [Smart Invites](https://docs.cronofy.com/developers/calendar-and-availability/calendar-events/smart-invites/index.md) send trackable invites
without needing access to the recipient's calendar.

- [Calendar Webhooks](https://docs.cronofy.com/api-reference/calendar-control/push-notifications/index.md)
keep your application up to date with changes in real time.

- [Event Triggers](https://docs.cronofy.com/api-reference/calendar-control/event-triggers/index.md)
drive your workflows from calendar and event data.

- [Application Calendars](https://docs.cronofy.com/developers/calendar-and-availability/calendar-events/application-calendars/index.md) stand in
for end-user or resource calendars when there's no calendar to connect.

- [Attachments](https://docs.cronofy.com/api-reference/calendar-control/event-attachments/index.md)
add files to the events your application creates.

[UI Elements](https://docs.cronofy.com/api-reference/ui-elements/index.md)
