Khal is a standards based CLI and terminal calendar program, able to synchronize with CalDAV servers through vdirsyncer.

(or rather: limitations)

• khal can read and write events/icalendars to vdir, so vdirsyncer can be used to synchronize calendars with a variety of other programs, for example CalDAV servers.
• fast and easy way to add new events
• ikhal (interactive khal) lets you browse and edit calendars and events
• no support for editing the timezones of events yet
• works with python 3.8+
• khal should run on all major operating systems [1]

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 or via IRC (#pimutils on Libera.Chat).

For khal's documentation have a look at readthedocs.

khal is packaged for most operating systems and should be installable with your standard package manager.

For some exemplary OS you can find installation instructions below. Otherwise see the documentation for more information.

apt install khal

nix-env -i khal

pacman -S khal

brew install khal

dnf install khal

pkg install py-khal

pip install git+https://github.com/pimutils/khal

Projects with similar aims you might want to check out are calendar-cli (no offline storage and a bit different scope) and gcalcli (only works with google's calendar).

You want to contribute to khal? Awesome!

The most appreciated way of contributing is by supplying code or documentation, reporting bugs, creating packages for your favorite operating system, making khal better known by telling your friends about it, etc.
