CalDAV
CalDAV (Calendar Extensions to WebDAV) is an internet protocol that allows clients to access and manage calendar data on a remote server, enabling calendar sharing, scheduling, and synchronization across devices and applications. It extends the WebDAV protocol with calendar-specific features like events, tasks, and free/busy time queries, commonly used for personal and enterprise calendar systems.
Developers should learn CalDAV when building calendar applications, integrating scheduling features into software, or implementing cross-platform calendar synchronization, as it provides a standardized way to handle calendar data over HTTP. It's essential for projects involving calendar sharing in collaborative tools, mobile apps with calendar sync, or enterprise systems requiring interoperable scheduling with clients like Apple Calendar, Mozilla Thunderbird, or custom solutions.
