iCalendar
iCalendar (Internet Calendaring and Scheduling Core Object Specification) is a standard data format for exchanging calendar and scheduling information between applications and systems. It defines a common format for representing events, tasks, and other calendar data, enabling interoperability across different platforms and software. The format is widely used for sharing calendar invites, synchronizing schedules, and integrating with email and productivity tools.
Developers should learn iCalendar when building applications that involve calendar functionality, such as event management systems, scheduling tools, or email integrations, as it provides a standardized way to handle calendar data exchange. It is essential for implementing features like sending meeting invites, syncing with external calendars (e.g., Google Calendar, Outlook), or parsing calendar data from various sources to ensure compatibility and avoid vendor lock-in.
