Usage Guidelines

• Time format: RFC3339 — 2024-01-15T09:00:00Z (UTC) or 2024-01-15T09:00:00+09:00 (with timezone).
• All-day events: use date format YYYY-MM-DD with all_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.
