vdirsyncer syncs CalDAV calendars to local .ics files. khal reads and writes them.

Sync First

Always sync before querying or after making changes:

vdirsyncer sync

View Events

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

Search

khal search "meeting"
khal search "dentist" --format "{start-date} {title}"

Create Events

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

Edit Events (interactive)

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 summary
  • d → edit description
  • t → edit datetime range
  • l → edit location
  • D → delete event
  • n → skip (save changes, next match)
  • q → quit

After editing, sync:

vdirsyncer sync

Delete Events

Use khal edit, then press D to delete.

Output Formats

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}

Caching

khal caches events in ~/.local/share/khal/khal.db. If data looks stale after syncing:

rm ~/.local/share/khal/khal.db
