Screenshots

OS, version, khal version and how you installed it:

• The output of khal --version: khal, version 0.11.3
• Installation method brew install khal
• python version: I have multiple but the default is currently 3.11.7
• OS: MacOS 14.4.1
• Your khal config file:

[calendars]

[[personal]]
path = PATH_TO_MY_FILE
type = calendar

[locale]
timeformat = %H:%M
dateformat = %Y-%m-%d
longdateformat = %Y-%m-%d
datetimeformat = %Y-%m-%d %H:%M
longdatetimeformat = %Y-%m-%d %H:%M

[default]
default_calendar = personal

• The versions of your other python packages: empty

Start at the CLI entry point for khal list and inspect how its options are defined. Confirm the expected --json title behavior and add coverage for the command; it is done when the option is accepted instead of producing a no-option error.
