Apple Reminders and Calendar CLI (event)

Use the event CLI to manage Apple Reminders and Calendars directly from the terminal. You can create, view, search, update, and delete reminders and calendar events, and sync data across devices.

Invocation & Arguments

Treat $ARGUMENTS as a free-form natural-language instruction and map it to the appropriate event command(s) documented below. Resolve relative dates and times ("tomorrow", "next Monday", "in 2 hours", "this Friday afternoon") against the current date/time before building the command. Examples:

• /apple-events remind me to call the dentist tomorrow at 3pm -> event reminders create ...
• /apple-events what's on my calendar this week? -> event calendar list ...
• /apple-events block 2-4pm Friday for deep work -> event calendar create ...

When no arguments are given

If $ARGUMENTS is empty, do not default to listing. Instead, infer intent from the current conversation:

1. Scan the recent conversation for an actionable item the user might want captured — a commitment, deadline, follow-up, meeting, appointment, or TODO.
2. Classify it:

- A task (something to do, optionally with a due date) -> a reminder (event reminders create). - A scheduled event (something happening at a specific time, with a start/end) -> a calendar event (event calendar create).

1. Confirm with the AskUserQuestion tool before creating anything. Present the inferred type and details (title, date/time, target list/calendar) so the user can confirm, switch task<->event, adjust fields, or decline. Never create in the no-args path without explicit confirmation.
2. If nothing actionable is found in the conversation, use AskUserQuestion to ask what the user would like to create (task or event) rather than guessing.

Setup & Constraints

event runs on macOS and Linux, with platform-specific storage backends. All reminder/calendar/list commands below behave identically on both; only the underlying store differs.

• macOS — reads and writes Apple Reminders and Calendar directly via EventKit.

- Requires Reminders.app and Calendar.app to be accessible. - If prompted, the user must grant Full Access permissions in System Settings > Privacy & Security > Reminders / Calendars. - Some advanced reminder fields (tags, flagged, url, parentTitle) require the AdvancedReminderEdit Shortcut to be installed (https://www.icloud.com/shortcuts/b578334075754da9ba6e50b501515808). Without it — or with the global --no-shortcuts flag — the basic reminder is still created and those fields are skipped with a printed note.

• Linux (and other non-Apple platforms) — there is no EventKit, so event reads and writes a local SQLite database at ~/.local/share/event-sync/local.db. Run event sync first to populate it from the Cloudflare D1 backend (see [Cloud Sync](#cloud-sync)), then use the same commands to manage that local data. Advanced fields and the AdvancedReminderEdit Shortcut are macOS-only.

General Usage

All commands support the --json flag to output results in JSON format, which is easier to parse.

Parsing completion state — never grep the text markers on JSON. The default text output marks completed reminders with - [x] and incomplete with - [ ]. The --json output has no such markers: it encodes each reminder as an object with a boolean isCompleted field. So to count or filter completed/incomplete from --json, parse isCompleted (e.g. jq '[.[] | select(.isCompleted)] | length', or a Python json pass) — never grep "[x]" against JSON, which always returns 0 and falsely reads every reminder as incomplete.

Reminders Management

List & Search Reminders

• List incomplete reminders: event reminders list — completed reminders are hidden by default (matches Reminders.app). A task you marked done disappears from this view; that is expected, not a deletion or a sync failure — the task still exists and its completion state syncs.
• List including completed: event reminders list --completed — always use this when you need to confirm a task's completion state, including verifying that a completion synced to another device.
• Filter by specific list: event reminders list --list "List Name"
• Filter by a due-date window (both bounds required, day-based, end exclusive):

event reminders list --start "2026-08-01" --end "2026-09-01" — the start day is inclusive and the end day exclusive, matching calendar list. To include reminders due on a given day, set --end to the day AFTER it (e.g. --end "2026-09-01" includes reminders through August 31). Bounds must be date-only yyyy-MM-dd; a time component is rejected with an invalid-date error. No --json is needed for human-readable output; the default markdown output works without the flag.

• To programmatically check completion, add --json and read the isCompleted boolean per item — do not grep "[x]" on JSON (see [General Usage](#general-usage)).
• Filter by a due-date window (both bounds required, day-based, end exclusive):

event reminders list --start "2026-08-01" --end "2026-09-01" — the start day is inclusive and the end day exclusive, matching calendar list. To include reminders due on a given day, set --end to the day AFTER it (e.g. --end "2026-09-01" includes reminders through August 31). Bounds must be date-only yyyy-MM-dd; a time component is rejected with an invalid-date error. No --json is needed for human-readable output; the default markdown output works without the flag.

• Search by keyword in title and notes: event reminders search --keyword "groceries" (also accepts --list and --completed)

Create Reminders

• Basic: event reminders create --title "Buy groceries"
• With details: event reminders create --title "Project meeting" --list "Work" --due "2026-03-10 14:00:00" --priority 1 --notes "Discuss Q3 goals"
• With multiline notes: event reminders create --title "Shopping list" --notes $'Milk\nBread\nEggs' (use $'...' with \n for newlines in bash/zsh)
• Advanced fields (require Shortcut): event reminders create --title "Urgent bug" --tags "bug,urgent" --flagged true --url "https://github.com/issues/1";
• Location trigger: event reminders create --title "Pick up keys" --location "Home" --latitude 37.3349 --longitude -122.0090 --proximity enter (--radius defaults to 100 meters; --proximity is enter or leave)
• With a URL: event reminders create --title "Fix login bug" --url "https://example.com/issues/42";. When a task is associated with an external link, always pass it via --url — never put URLs in --notes as a substitute. If the Shortcut isn't installed, --url is skipped gracefully with a printed note.
• Continuing coding/agent work: when a reminder tracks an in-progress coding or agent task tied to a specific project and Claude Code session, append a continuation command to --notes on its own line: Continue:\ncd <project-dir> && claude -r <session-id> (use $'...\n...' for the newline). Resolve <session-id> by finding the Claude Code session whose transcript actually holds the task's context — transcripts live at ~/.claude/projects/<encoded-cwd>/<session-id>.jsonl, so grep them by keyword rather than assuming the current session's id. Don't guess <project-dir> or <session-id>; confirm with AskUserQuestion if either is unclear.

Update Reminders

• Mark as completed: event reminders update --id <UUID> --completed true (or --completed false to uncheck)
• Change title and priority: event reminders update --id <UUID> --title "New Title" --priority 5
• Add/remove flag (requires Shortcut): event reminders update --id <UUID> --flagged true or --flagged false
• Clear a date: event reminders update --id <UUID> --clear-due (or --clear-start)
• Remove location alarms: event reminders update --id <UUID> --clear-location

Delete Reminders

• Delete by ID: event reminders delete --id <UUID>

List Management

• List all reminder lists: event reminders lists list
• Create a list: event reminders lists create --name "New List Name"
• Rename a list: event reminders lists update --id <LIST-ID> --name "New Name"
• Delete a list: event reminders lists delete --id <LIST-ID>

Subtasks

• There is no dedicated subtasks subcommand. Create a subtask by giving a parent's title (requires the Shortcut): event reminders create --title "Subtask" --parent-title "Parent Task Title"
• Convert an existing reminder into a subtask: event reminders update --id <UUID> --parent-title "Parent Task Title"

Calendar Management

List Events

• List upcoming events (default 1 month from today): event calendar list
• List for a date range: event calendar list --start "2026-03-01" --end "2026-03-31"
• Filter by calendar: event calendar list --calendar "Work"

Create Events

• Timed event: event calendar create --title "Standup" --start "2026-03-10 09:00:00" --end "2026-03-10 09:30:00" --calendar "Work" --location "Office" --notes "Daily sync"
• With multiline notes: event calendar create --title "Conference" --start "2026-03-10 09:00:00" --end "2026-03-10 17:00:00" --notes $'Agenda:\nKeynote\nWorkshop\nBreakout sessions'
• All-day event: use yyyy-MM-dd for --start / --end.

Update & Delete Events

• Update: event calendar update --id <ID> --title "New Title" --start "2026-03-10 10:00:00" --end "2026-03-10 11:00:00"
• Delete: event calendar delete --id <ID> (for recurring events, --span controls scope)

Cloud Sync

Sync reminders, calendar events, and lists across devices through a Cloudflare D1 backend.

• Run a full bidirectional sync (pull, then push): event sync (equivalently event sync run)
• Check configuration and sync state: event sync status
• Configure the backend connection: event sync config --api-url <URL> --api-token <TOKEN> [--device-id <ID>] (writes ~/.config/event-sync/config.json; env vars take precedence when set)
• Advanced one-directional sync: event sync push / event sync pull (both accept --type reminders|calendar|lists|all)

On macOS, sync bridges EventKit and D1. On Linux, sync bridges the local SQLite database and D1 — so on a fresh Linux machine, event sync (or event sync pull) is the first step before any data is available to the other commands.

What syncs. Basic fields — including each reminder's completion state (isCompleted / completionDate) — plus url, location, alarms, recurrenceRules, and calendar attendees travel in the sync payload and are restored on pull, so they survive a cross-device sync. Tags, flagged status, and subtask relationships (parentTitle) are macOS/Shortcut-only and are not part of the sync payload; they must be set locally on each device.

Verifying a completion synced. After marking a task done on one device, confirm it reached another device with event reminders list --completed on that device (or event sync reminders list to read the cloud store directly). Because event reminders list hides completed tasks by default, a task's absence from that default view does not mean the completion failed to sync.

D1-direct subcommands bypass local storage and read/write the cloud backend directly: event sync reminders list / event sync reminders create, and event sync calendar list. Use these to inspect or seed the cloud store without touching EventKit or the local SQLite DB.

Sync requires a configured Cloudflare D1 backend: set the EVENTSYNCAPIURL and EVENTSYNCAPITOKEN environment variables (the device id defaults to the hostname). Reminders and calendar events are also end-to-end encrypted, so sync requires EVENTENCRYPTIONKEY — a base64-encoded 32-byte key (openssl rand -base64 32) that must be identical on every device; reminder/calendar push and pull fail if it is unset or mismatched (lists are not encrypted). For one-time Worker deployment, key generation, and per-device environment setup, see [references/cloud-sync.md](references/cloud-sync.md). The canonical Worker is shared with the note CLI: deploy it once serving all five tables (migrations/all) and point both CLIs at the same URL and token. The Worker source is not bundled here — ./references/fetch-worker.sh fetches it on demand into a gitignored references/worker/.

Limitations & Notes

• Dates: timed values use yyyy-MM-dd HH:mm:ss (e.g. "2026-03-10 14:00:00"); all-day calendar events use yyyy-MM-dd.
• Priority: 1 = High, 5 = Medium, 9 = Low, 0 = None.
• Advanced fields: tags, flagged, url, and subtask relationships (parentTitle) are handled via the AdvancedReminderEdit Shortcut. Without it (or with --no-shortcuts) they are skipped. The reminder notes field holds plain user notes only — no metadata block.
• Notes formatting: newlines in --notes are preserved as plain text line breaks; markdown syntax (bold, italic, lists, etc.) is not interpreted and will appear literally. Bullet characters (•) must be written as - instead.
• Calendar sync window: only events from one year in the past to two years ahead are pushed and pulled. Events moved outside this window remain in the cloud until explicitly deleted locally.
• Sync conflicts: timed entities use last-write-wins using modification timestamps (falling back to creation time). Local copies without any timestamp are not overwritten on pull.
• Reminder lists: no per-list modification timestamp — concurrent renames last-write-wins on pull.
• Advanced fields on sync: tags, flagged, and subtask relationships (parentTitle) are macOS/Shortcut-only and are not synced; use local Shortcut-backed commands for those fields. In contrast, url, location, alarms, recurrenceRules, and calendar attendees travel in the sync payload and are restored on pull.
• Encryption: reminders and calendar events are end-to-end encrypted with AES-GCM before upload; the cloud only ever stores ciphertext for those fields (title, list, and dates stay plaintext for search). This requires EVENTENCRYPTIONKEY to be set and identical across devices — see [Cloud Sync](#cloud-sync). Lists carry no sensitive data and are not encrypted.
