Updates an access control rule for a calendar using patch semantics (partial update). This allows modifying specific fields without affecting other properties. Note: Each patch request consumes three quota units. For domain-type ACL rules, if PATCH fails with 500 error, this action will automatically fallback to UPDATE method.

Inserts an existing calendar into the user's calendar list.

Updates an existing entry on the user\'s calendar list.

Deletes a secondary calendar. Use calendars.clear for clearing all events on primary calendars.

Updates metadata for a calendar.

Clears a primary calendar. This operation deletes all events associated with the primary calendar of an account.

Create a Google Calendar event using `start_datetime` plus `event_duration_hour` and `event_duration_minutes` fields to derive the end time. Requires calendar write access. The organizer is added as an attendee unless `exclude_organizer` is True. Example request to create event for 1 hour 30 minutes: { "calendar_id": "primary", "start_datetime": "2025-01-16T13:00:00", "timezone": "America/New_York", "event_duration_hour": 1, "event_duration_minutes": 30, "summary": "Client sync", "attendees": [{"email": "[email protected]"}] }

Deletes a specified event by `event_id` from a Google Calendar (`calendar_id`); this action is idempotent and raises a 404 error if the event is not found.

Creates a new, empty Google Calendar with the specified title (summary).

Returns instances of the specified recurring event.

Returns events on the specified calendar.

Moves an event to another calendar, i.e., changes an event's organizer.

Watch for changes to Events resources.

Finds events in a specified Google Calendar using text query, time ranges (event start/end, last modification), and event types; ensure `timeMin` is not chronologically after `timeMax` if both are provided.

Finds both free and busy time slots in Google Calendars for specified calendars within a defined time range (defaults to the current day UTC if `time_min`/`time_max` are omitted). Returns busy intervals enriched with event details and calculates free slots by finding gaps between busy periods; `time_min` must precede `time_max` if both are provided. This action retrieves free and busy time slots for the specified calendars over a given time period. It analyzes the busy intervals from the calendars and provides calculated free slots based on the gaps in the busy periods.

Returns free/busy information for a set of calendars.

Retrieves a specific Google Calendar, identified by `calendar_id`, to which the authenticated user has access.

Gets the current date and time, allowing for a specific timezone offset.

Retrieves the list of access control rules (ACLs) for a specified calendar, providing the necessary 'rule_id' values required for updating specific ACL rules.

Retrieves a paginated list of calendars from the user's calendar list, with optional filtering and sync capabilities.

Partially updates (PATCHes) an existing Google Calendar, modifying only the fields provided; `summary` is mandatory and cannot be an empty string, and an empty string for `description` or `location` clears them.
