Khal is a standards based CLI (console) calendar program. CalDAV compatibility is achieved by using vdir/vdirsyncer as a backend, allowing syncing of calendars with a variety of other programs on a host of different platforms.

khal is currently in an early stage of development, has a limited feature set and is probably full of bugs. If you do try it out please report back any bugs you might encounter.

(or rather: limitations)

• khal can read and write events/icalendars to vdir
• fast and easy way to add new events
• ikhal (interactive khal) lets you browse and edit calendars and events
• support for recurring events is not complete yet, they cannot be deleted or edited and some recursion patterns are not understood yet
• you cannot edit the timezones of events
• khal should run on all major operating systems¹ (has been tested on FreeBSD and Debian GNU/Linux)

Please do provide feedback if khal works for you or even more importantly if it doesn't. The preferred way to get in contact (especially if something isn't working) is via github, otherwise you can reach me (the original author via email at khal (at) lostpackets (dot) de , by jabber/XMPP at geier (at) jabber (dot) ccc (dot) de.

For khal's documentation have a look at the website or readthedocs.
