history
Project history and usage
calcurse is a curses-based personal organizer for the command line, combining calendar, appointments, TODOs, notifications, iCalendar import/export, scripting-friendly output, and later CalDAV synchronization. It is a classic Unix productivity package: terminal UI first, plain local data, and automation hooks.
Project history
The official site describes calcurse as a command-line calendar and scheduling application for events, appointments, and everyday tasks, with a configurable notification system and a curses interface. Its release notes begin with version 1.0 on 8 October 2005 and continue through modern 4.x releases.
Over time calcurse added recurring appointments, internationalization, UTF-8 support, import/export, user-configurable key bindings, hooks, CalDAV support, and command-line filtering/formatting. Version 4.0.0 in 2015 marks a later modernization point in the release stream, while 4.8.x releases in the 2020s show continued maintenance.
Adoption history
calcurse became popular among terminal-first users who wanted a lightweight alternative to graphical calendar applications and web services. The official site explicitly highlights command-line options suitable for scripts, version-control hooks for calendar data, and CalDAV synchronization for mobile-device interoperability.
Its package-manager footprint is broad for a small TUI application, appearing in Homebrew and major Linux distributions because it has few conceptual moving parts: install the binary, keep data in user config/data directories, and automate around text-friendly commands.
How it is used
Users run `calcurse` for the full-screen TUI, `calcurse-caldav` for synchronization, and helper tools such as `calcurse-upgrade` or `calcurse-vdir` for data migration and vdir workflows. It is often used locally with cron, shell scripts, mail notifications, and version control hooks.
The package stores user configuration and key bindings in calcurse config files, while CalDAV credentials are typically kept in the caldav config file, making the credential path relevant for audits and backup tooling.
Why package nerds care
calcurse matters because it is a rare survivor in the terminal organizer category: small enough to package everywhere, practical enough to replace a GUI calendar for some users, and scriptable enough to participate in Unix workflows.
For package nerds, the interesting history is its evolution from a 2005 curses calendar into a tool with iCalendar, CalDAV, hooks, vdir-style workflows, and distribution packaging without losing the command-line-first model.
