Calcurse

What is Calcurse?

Calcurse is a terminal-based personal information manager that combines a calendar with a to-do list. It has been maintained for years and remains a staple in the text-mode PDA genre. Unlike graphical suites, it stores data in simple text files, making it easy to back up and edit with any text editor.

This tool targets developers, sysadmins, and minimalists who live in the terminal. If you already use Vim or Emacs for daily work, Calcurse fits naturally into that environment. It avoids the overhead of GUI applications, allowing you to manage schedules without leaving your current workflow.

Compared to Windows Calendar or Outlook, Calcurse lacks visual flair and drag-and-drop features. However, it offers faster data access and a lower memory footprint. The experience is purely functional: you navigate dates and tasks using keyboard shortcuts, which can feel restrictive at first but becomes highly efficient with practice.

Best for: Terminal-centric users who want a fast, low-maintenance way to track events and tasks without GUI overhead.

Tips for Windows users

Coming from Windows Calendar, you will need to learn a new set of keyboard shortcuts. There is no direct file import for standard .ics files without external tools, so plan to re-enter initial data or use a converter. The workflow is linear: you navigate to a date to add an event, rather than clicking and dragging. Keep your data files in a synced folder if you need access across machines, as Calcurse does not handle network sync itself.
