File contents

apple-cal-anywhere

Advanced Apple Calendar integration using CalDAV (RFC 4791) and Managed Attachments (RFC 8607).

Primary CLI

scripts/applecal.py

Capabilities

Event CRUD: List, Create, Update, Delete.
Multi-Calendar Support: Query multiple calendars in a single command.
True Attachments: RFC 8607 compatible (works on iPhone/iPad).
Free/Busy: CalDAV scheduling lookup with event-derived fallback.

Common Commands

List Events (Combined)

Check multiple calendars at once:

python3 scripts/applecal.py events list \
  --apple-id your@icloud.com \
  --calendar Family \
  --calendar Work \
  --from "2026-02-26T00:00:00Z" \
  --to "2026-02-26T23:59:59Z"

Create All-Day Event

python3 scripts/applecal.py events create \
  --apple-id your@icloud.com \
  --calendar Family \
  --summary "Birthday" \
  --start "2026-02-26" \
  --end "2026-02-26" \
  --all-day

Attach a File (iPhone Safe)

python3 scripts/applecal.py attach add \
  --apple-id your@icloud.com \
  --calendar Family \
  --uid <UID> \
  --file /path/to/document.pdf

Free/Busy Check

python3 scripts/applecal.py freebusy \
  --apple-id your@icloud.com \
  --calendar Family \
  --from "2026-02-26T00:00:00Z" \
  --to "2026-02-26T23:59:59Z"

Notes

Birthdays: The virtual "Birthdays" calendar is not searchable via CalDAV. Key birthdays should be added as physical recurring events in the Family calendar for agent visibility.
Auth: Resolution order is APPLECAL_PASSWORD → Python keyring (if installed/configured) → macOS Keychain fallback. Run doctor to verify connectivity.
Event update clearing: Use events update --clear-location / --clear-description to explicitly remove optional fields.
Attachment safety: attach add blocks sensitive paths/names, allowlists file extensions, and supports optional directory scoping via APPLECAL_ATTACH_DIR.
Apple ID: Always pass --apple-id your@icloud.com (the iCloud account email, not necessarily your Apple ID login).
