# Apple Calendar CLI (accli)
## Installation
```bash
npm install -g @joargp/accli
```
**Requirements:** macOS only (uses JavaScript for Automation)
## Overview
The accli tool provides command-line access to macOS Apple Calendar. It enables listing calendars, querying events, creating/updating/deleting events, and checking availability across calendars.
## Quick Reference
### DateTime Formats
- Timed events: YYYY-MM-DDTHH:mm or YYYY-MM-DDTHH:mm:ss
- All-day events: YYYY-MM-DD
### Global Options
- --json - Output as JSON (recommended for parsing)
- --help - Show help for any command
## Commands
### List Calendars
```
accli calendars [--json]
```
Lists all available calendars with names and persistent IDs. Run this first to discover available calendars and their IDs.
### List Events
```
accli events <calendarName> [options]
```
Options:
- --calendar-id <id> - Persistent calendar ID (recommended over name)
- --from <datetime> - Start of range (default: now)
- --to <datetime> - End of range (default: from + 7 days)
- --max <n> - Maximum events to return (default: 50)
- --query <q> - Case-insensitive filter on summary/location/description
- --json - Output JSON
Examples:
```bash
# Events from Work calendar for this week
accli events Work --json
# Events in January
accli events Work --from 2025-01-01 --to 2025-01-31 --json
# Search for specific events
accli events Work --query "standup" --max 10 --json
```
### Get Single Event
```
accli event <calendarName> <eventId> [--json]
```
Retrieves details for a specific event by its ID.
### Create Event
```
accli create <calendarName> --summary <s> --start <datetime> --end <datetime> [options]
```
Required Options:
- --summary <s> - Event title
- --start <datetime> - Start time
- --end <datetime> - End time
Optional:
- --location <l> - Event location
- --description <d> - Event description
- --all-day - Create an all-day event
- --json - Output JSON
Examples:
```bash
# Create a timed meeting
accli create Work --summary "Team Standup" --start 2025-01-15T09:00 --end 2025-01-15T09:30 --json
# Create an all-day event
accli create Personal --summary "Vacation" --start 2025-07-01 --end 2025-07-05 --all-day --json
# Create with location and description
accli create Work --summary "Client Meeting" --start 2025-01-15T14:00 --end 2025-01-15T15:00 \
--location "Conference Room A" --description "Q1 planning discussion" --json
```
### Update Event
```
accli update <calendarName> <eventId> [options]
```
Options (all optional - only provide what to change):
- --summary <s> - New title
- --start <datetime> - New start time
- --end <datetime> - New end time
- --location <l> - New location
- --description <d> - New description
- --all-day - Convert to all-day event
- --no-all-day - Convert to timed event
- --json - Output JSON
Example:
```bash
accli update Work event-id-123 --summary "Updated Meeting Title" --start 2025-01-15T15:00 --end 2025-01-15T16:00 --json
```
### Delete Event
```
accli delete <calendarName> <eventId> [--json]
```
Permanently deletes an event. Confirm with user before executing.
### Check Free/Busy
```
accli freebusy --calendar <name> --from <datetime> --to <datetime> [options]
```
Options:
- --calendar <name> - Calendar name (can repeat for multiple calendars)
- --calendar-id <id> - Persistent calendar ID (can repeat)
- --from <datetime> - Start of range (required)
- --to <datetime> - End of range (required)
- --json - Output JSON
Shows busy time slots, excluding cancelled, declined, and transparent events.
Examples:
```bash
# Check availability across calendars
accli freebusy --calendar Work --calendar Personal --from 2025-01-15 --to 2025-01-16 --json
# Check specific hours
accli freebusy --calendar Work --from 2025-01-15T09:00 --to 2025-01-15T18:00 --json
```
### Configuration
```bash
# Set default calendar (interactive)
accli config set-default
# Set default by name
accli config set-default --calendar Work
# Show current config
accli config show
# Clear default
accli config clear
```
When a default calendar is set, commands automatically use it if no calendar is specified.
## Workflow Guidelines
### Before Creating Events
1. List calendars to get available calendar names/IDs
2. Check free/busy to find available time slots
3. Confirm event details with user before creating
### Best Practices
- Always use --json flag for programmatic parsing
- Prefer --calendar-id over calendar names for reliability
- When querying events, start with reasonable date ranges
- Confirm with user before delete operations
- Use ISO 8601 datetime format consistently
### Common Patterns
Find a free slot and schedule:
```bash
# 1. Check availability
accli freebusy --calendar Work --from 2025-01-15T09:00 --to 2025-01-15T18:00 --json
# 2. Create event in available slot
accli create Work --summary "Meeting" --start 2025-01-15T14:00 --end 2025-01-15T15:00 --json
```
View today's schedule:
```bash
accli events Work --from $(date +%Y-%m-%d) --to $(date -v+1d +%Y-%m-%d) --json
```
This skill provides command-line control over Apple Calendar on macOS for listing calendars, reading events, creating/updating/deleting events, and checking free/busy availability. It is designed to be used when you need programmatic or scripted access to your macOS calendar data. Use it to automate scheduling workflows and to integrate calendar checks into other tools.
The skill invokes the accli command-line tool (macOS-only) to query and manipulate Apple Calendar via JavaScript for Automation. It lists calendars with persistent IDs, fetches events in date ranges, creates and updates events with ISO 8601 timestamps, deletes events after confirmation, and reports free/busy slots across one or more calendars. JSON output is available for reliable parsing and automation.
Is this skill available on Windows or Linux?
No. This skill uses macOS JavaScript for Automation and only works on macOS.
How should I format dates and times?
Use ISO 8601: YYYY-MM-DD for all-day events and YYYY-MM-DDTHH:mm or YYYY-MM-DDTHH:mm:ss for timed events.
