Sync and query CalDAV calendars (iCloud, Google, Fastmail, Nextcloud, etc.) using vdirsyncer + khal. Works on Linux.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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:
```bash
vdirsyncer sync
```
## View Events
```bash
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
```bash
khal search "meeting"
khal search "dentist" --format "{start-date} {title}"
```
## Create Events
```bash
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:
```bash
vdirsyncer sync
```
## Edit Events (interactive)
`khal edit` is interactive — requires a TTY. Use tmux if automating:
```bash
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

How to install
mdr add pr-e/openclaw-master-skills/caldav-calendar@sha256:63b956dec3a22bc0The line at the top of this page pins the label git:20260311.3e83cee, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
