# list_calendars

> List the authenticated user's calendars with their display names and CalDAV URLs.

Lists the user's calendars. The returned CalDAV URL is the `calendarUrl` value that the event tools take to target a specific calendar; omit it there to use the default calendar.

## Parameters

This tool takes no parameters.

## Example

```json Call theme={null}
{}
```

```text Result theme={null}
2 calendar(s):

1. Personal
   url: https://mail.langmail.me/dav/cal/you/default/

2. Marketing
   url: https://mail.langmail.me/dav/cal/you/a1b2c3/
```

A user with no calendars gets `No calendars found.`
