Google Calendar
Unclaimed verified 12 jul 2026TL;DR

It is designed for both individual users and large organizations, with its primary differentiator being its native, seamless integration with the Google Workspace ecosystem and Gmail.

Our Take
Google Calendar remains the market leader in the scheduling space, functioning as the backbone for productivity in both professional and personal contexts. Its position is solidified by its 'zero-friction' experience for Android and Workspace users, where events like flights or restaurant reservations are automatically synced from email. While it offers robust shared calendar features that are essential for team coordination, it occasionally lacks the deep project-management granularity found in specialized tools like Notion or Monday.com. For the vast majority of users, its simplicity and reliability outweigh the lack of advanced visual customization. It is best suited for teams that rely on Google Meet and Gmail, providing a centralized hub that requires almost no learning curve for new users.

Agent Readiness
74/100Google Calendar is exceptionally 'agent-ready' due to its comprehensive REST API, mature OAuth2 implementation, and extensive support for webhooks (push notifications). Its documentation is top-tier, providing an API Explorer (sandbox) that allows developers and AI agents to test calls directly in the browser, while its massive presence in automation platforms like Zapier and Make ensures seamless connectivity with almost any other service.

GOOGLECALENDAR_ACL_PATCHUpdates 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.GOOGLECALENDAR_CALENDAR_LIST_INSERTInserts an existing calendar into the user's calendar list.GOOGLECALENDAR_CALENDAR_LIST_UPDATEUpdates an existing entry on the user\'s calendar list.GOOGLECALENDAR_CALENDARS_DELETEDeletes a secondary calendar. Use calendars.clear for clearing all events on primary calendars.GOOGLECALENDAR_CALENDARS_UPDATEUpdates metadata for a calendar.GOOGLECALENDAR_CLEAR_CALENDARClears a primary calendar. This operation deletes all events associated with the primary calendar of an account.GOOGLECALENDAR_CREATE_EVENTCreate 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]"}] }GOOGLECALENDAR_DELETE_EVENTDeletes 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.GOOGLECALENDAR_DUPLICATE_CALENDARCreates a new, empty Google Calendar with the specified title (summary).GOOGLECALENDAR_EVENTS_INSTANCESReturns instances of the specified recurring event.GOOGLECALENDAR_EVENTS_LISTReturns events on the specified calendar.GOOGLECALENDAR_EVENTS_MOVEMoves an event to another calendar, i.e., changes an event's organizer.GOOGLECALENDAR_EVENTS_WATCHWatch for changes to Events resources.GOOGLECALENDAR_FIND_EVENTFinds 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.GOOGLECALENDAR_FIND_FREE_SLOTSFinds 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.GOOGLECALENDAR_FREE_BUSY_QUERYReturns free/busy information for a set of calendars.GOOGLECALENDAR_GET_CALENDARRetrieves a specific Google Calendar, identified by `calendar_id`, to which the authenticated user has access.GOOGLECALENDAR_GET_CURRENT_DATE_TIMEGets the current date and time, allowing for a specific timezone offset.GOOGLECALENDAR_LIST_ACL_RULESRetrieves the list of access control rules (ACLs) for a specified calendar, providing the necessary 'rule_id' values required for updating specific ACL rules.GOOGLECALENDAR_LIST_CALENDARSRetrieves a paginated list of calendars from the user's calendar list, with optional filtering and sync capabilities.GOOGLECALENDAR_PATCH_CALENDARPartially 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.GOOGLECALENDAR_PATCH_EVENTUpdate specified fields of an existing event in a Google Calendar using patch semantics (array fields like `attendees` are fully replaced if provided); ensure the `calendar_id` and `event_id` are valid and the user has write access to the calendar.GOOGLECALENDAR_QUICK_ADDParses natural language text to quickly create a basic Google Calendar event with its title, date, and time, suitable for simple scheduling; does not support direct attendee addition or recurring events, and `calendar_id` must be valid if not 'primary'.GOOGLECALENDAR_REMOVE_ATTENDEERemoves an attendee from a specified event in a Google Calendar; the calendar and event must exist.GOOGLECALENDAR_SETTINGS_LISTReturns all user settings for the authenticated user.GOOGLECALENDAR_SETTINGS_WATCHWatch for changes to Settings resources.GOOGLECALENDAR_SYNC_EVENTSSynchronizes Google Calendar events, performing a full sync if no `sync_token` is provided or if a 410 GONE error (due to an expired token) necessitates it, otherwise performs an incremental sync for events changed since the `sync_token` was issued.GOOGLECALENDAR_UPDATE_ACL_RULEUpdates an access control rule for the specified calendar.GOOGLECALENDAR_UPDATE_EVENTUpdates an existing event by `event_id` in a Google Calendar; this is a full PUT replacement, so provide all desired fields as unspecified ones may be cleared or reset.
