vdirsyncer syncs CalDAV calendars to local .ics files. khal reads and writes them.
Always sync before querying or after making changes:
vdirsyncer sync
khal list # Today
khal list today 7d # Next 7 days
khal list tomorrow # Tomorrow
khal list 2026-01-15 2026-01-20 # Date range
khal list -a Work today # Specific calendar
khal search "meeting"
khal search "dentist" --format "{start-date} {title}"
khal new 2026-01-15 10:00 11:00 "Meeting title"
khal new 2026-01-15 "All day event"
khal new tomorrow 14:00 15:30 "Call" -a Work
khal new 2026-01-15 10:00 11:00 "With notes" :: Description goes here
After creating, sync to push changes:
vdirsyncer sync
khal edit is interactive — requires a TTY. Use tmux if automating:
khal edit "search term"
khal edit -a CalendarName "search term"
khal edit --show-past "old event"
Menu options:
s → edit summaryd → edit descriptiont → edit datetime rangel → edit locationD → delete eventn → skip (save changes, next match)q → quitAfter editing, sync:
vdirsyncer sync
Use khal edit, then press D to delete.
For scripting:
khal list --format "{start-date} {start-time}-{end-time} {title}" today 7d
khal list --format "{uid} | {title} | {calendar}" today
Placeholders: {title}, {description}, {start}, {end}, {start-date}, {start-time}, {end-date}, {end-time}, {location}, {calendar}, {uid}
khal caches events in ~/.local/share/khal/khal.db. If data looks stale after syncing:
rm ~/.local/share/khal/khal.db
