## What it is
calcurse is a text-based (ncurses) calendar and scheduling application for the command line that tracks events, appointments, and TODO items. It offers a customizable curses interface, notifications, iCalendar import/export, experimental CalDAV sync, and a non-interactive CLI suitable for scripting.

## Use cases
- manage appointments and todo lists from the terminal
- get reminders for upcoming deadlines
- import and export iCalendar files
- sync calendar with mobile devices via CalDAV
- query upcoming appointments in shell scripts
- keep calendar data under version control with hooks

## When to choose
- you want a lightweight, keyboard-driven calendar in a terminal
- you need scriptable, non-interactive access to your schedule
- you prefer plain-text data files you can back up or version-control yourself
- you work primarily on Linux/BSD/macOS servers or without a GUI

## When to avoid
- you need a graphical calendar with rich visual layouts
- you require fully mature CalDAV two-way sync (it is experimental)
- you need shared/team calendars or collaboration features
- you want a mobile or web-based calendar client
