# Another calendar

[Connectors](https://lumman.co/mcp) / [Multi Calendar](https://lumman.co/mcp/multi-calendar)

Fastmail, Zoho, GMX and other calendars on a CalDAV server connect to Multi Calendar with their address and password.

Multi Calendar finds Fastmail, GMX, WEB.DE, mail.com and Zoho calendars from the address alone, and shows where each makes the password it takes. Any other calendar server is found from your domain's records, or from the address you type.

1. [Add to Claude](https://claude.ai/directory/connectors/lumman-multi-calendar) - Opens claude.ai - press Connect there.
2. Sign in, add your calendar and approve Claude in the window Claude opens - choose Fastmail, Zoho, GMX or another, type the address and paste its password when it asks.
