libical

Libical is an open-source C library that implements the iCalendar (RFC 5545) and vCard (RFC 6350) standards for calendar and contact data interchange. It provides parsing, generation, and manipulation of iCalendar and vCard data, enabling applications to handle scheduling, events, and contact information in a standardized format. The library is widely used in email clients, calendar applications, and groupware systems to ensure interoperability across platforms.

Also known as: libical library, iCalendar library, vCard library, ical, libical-c

Why learn libical?

Developers should learn libical when building applications that need to process calendar events, appointments, or contact data, such as email clients (e.g., Evolution), calendar sync tools, or scheduling software. It is essential for ensuring compliance with iCalendar and vCard standards, which are critical for cross-platform compatibility in personal information management (PIM) systems. Use cases include parsing .ics files for event imports, generating calendar invites, or integrating with CalDAV servers for calendar synchronization.
