Notes

All date/time values must include timezone offsets (e.g., -08:00 for PST). The system automatically retrieves the user’s timezone from Google Calendar settings. When listing events without specifying a date range, it defaults to the current day in the user’s timezone. Recurring events use RRULE format for recurrence patterns. Maximum 2500 events can be retrieved per request.
