{/* MANUAL-CONTENT-START:intro */}
[Google Calendar](https://calendar.google.com) is Google's powerful calendar and scheduling service that provides a comprehensive platform for managing events, meetings, and appointments. With seamless integration across Google's ecosystem and widespread adoption, Google Calendar offers robust features for both personal and professional scheduling needs.

With Google Calendar, you can:

- **Create and manage events**: Schedule meetings, appointments, and reminders with detailed information
- **Send calendar invites**: Automatically notify and coordinate with attendees through email invitations
- **Natural language event creation**: Quickly add events using conversational language like "Meeting with John tomorrow at 3pm"
- **View and search events**: Easily find and access your scheduled events across multiple calendars
- **Manage multiple calendars**: Organize different types of events across various calendars

In Sim, the Google Calendar integration enables your agents to programmatically create, read, and manage calendar events. This allows for powerful automation scenarios such as scheduling meetings, sending calendar invites, checking availability, and managing event details. Your agents can create events with natural language input, send automated calendar invitations to attendees, retrieve event information, and list upcoming events. This integration bridges the gap between your AI workflows and calendar management, enabling seamless scheduling automation and coordination with one of the world's most widely used calendar platforms.
