       Caledonia is a command-line calendar client.

     

       4
       4
       +
       Currently, it operates on directories of [`.ics`](https://datatracker.ietf.org/doc/html/rfc5545) files (as managed by tools like [vdirsyncer](https://github.com/pimutils/vdirsyncer)).

     

       5
       5
       +
       It supports the `list` and `query` commands.

       +
       See [TODO](./TODO.org) for future plans.

       Caledonia looks for calendars in the directory specified by the `CALENDAR_DIR` environment variable or in `~/.calendars/` by default.
