Calendar

Calendar in the terminal.

Usage

calendar

View a day's events (styled in a terminal, plain when piped; force either with --color always / --color never):

calendar view [today]
calendar view tomorrow
calendar view yesterday
calendar view 2026-08-01

Add an event:

calendar add "Lunch with Will" --time 12:30 --duration 45m
calendar add Standup --date tomorrow --time 9:15 --duration 15m
calendar add Launch --date 2026-08-01 --all-day

[!NOTE] On first launch, allow your terminal to access Calendars in System Settings.

Installation

Install with Go:

go install github.com/maaslalani/calendar@latest

Or download a binary from the releases.

EventKit

calendar reads your events directly from Apple's native EventKit framework, so it shows the same calendars as Calendar.app.¹

Calendar File System

[!WARNING] Not Implemented.

Interact with your calendar as a file system. See 0001-calfs.md for the design.
