Usage Guidelines
- Time format: RFC3339 —
2024-01-15T09:00:00Z(UTC) or2024-01-15T09:00:00+09:00(with timezone). - All-day events: use date format
YYYY-MM-DDwithall_day=true. - Default calendar is
"primary".
Common Operations
Schedule a meeting: Use create_event with attendees parameter for full control over time, description, and reminders.
Find available time: Call check_availability with the relevant calendar IDs and time range before creating events to avoid conflicts.
Quick scheduling: quick_add_event accepts natural language (e.g., "Lunch with Sarah tomorrow at noon"). Convenient but less precise than create_event.
Reschedule: Use update_event with new start_time and end_time. Only the fields you provide will be changed.
