Caldav Calendar

This brings CalDAV calendar management into Claude through vdirsyncer and khal, so you can read, create, and edit events across iCloud, Google, Fastmail, Nextcloud, and other CalDAV providers without leaving your workflow. It's Linux-only and requires both tools installed. The sync-then-query pattern is straightforward: vdirsyncer pulls remote calendars to local .ics files, khal lets you list, search, and create events with simple commands, then you sync again to push changes. The interactive edit mode needs a TTY, so you'll want tmux if you're automating. Good for checking your schedule or adding events without context switching to a calendar app, though initial setup does require wrangling two config files.

Files

CalDAV Calendar (vdirsyncer + khal)

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"
