List upcoming events

node calendar-crab.js list --days=7 --max=20

Create an event

node calendar-crab.js create \
  --title="Team Sync" \
  --date=2026-03-20 \
  --time=10:00 \
  --duration=30 \
  --location="Zoom" \
  --attendees="alice@co.com,bob@co.com" \
  --description="Weekly sync" \
  --tz="America/Los_Angeles"

Move an event

# By date + time
node calendar-crab.js move --date=2026-03-20 --from=10:00 --to=14:00

# By event ID
node calendar-crab.js move --id="EVENT_ID" --to="2026-03-20T14:00:00-07:00"

Delete an event

node calendar-crab.js delete --id="EVENT_ID"
node calendar-crab.js delete --date=2026-03-20 --time=10:00

Configuration

Timezone can also be set per-command with --tz=America/Los_Angeles.

Execution rules

1. Always list first to verify the target event exists and is unique.
2. move and delete auto-notify all attendees (sendUpdates=all).
3. On failure, the raw Google API error is returned for debugging.

Setup

1. Go to Google Cloud Console and create a project.
2. Enable the Google Calendar API.
3. Create OAuth 2.0 credentials (Desktop app type).
4. Save the credentials as ~/.openclaw/secrets/google-calendar-oauth.json: json { "client_id": "YOUR_CLIENT_ID", "client_secret": "YOUR_CLIENT_SECRET" }
5. Obtain a refresh token via the OAuth flow and save as ~/.openclaw/secrets/google-calendar-token.json: json { "refresh_token": "YOUR_REFRESH_TOKEN", "access_token": "", "expires_in": 0, "obtained_at": "" } The script auto-refreshes the access token using the refresh token.

這是一個實用的小工具，安裝簡單無需額外依賴，核心的日曆管理功能都已具備，文件寫得清楚詳細。不過使用體驗還有提升空間，錯誤提示可以更友好一些，操作時的反饋資訊也能更直觀。總體來說功能紮實，是一個值得一試的工具。
