ICSCalDAV

ICSCalDAV is a term that can refer to the combination of two important internet standards: iCalendar (iCal) and CalDAV. iCalendar, often abbreviated as iCal, is a standardized internet message format for representing calendar and scheduling information. It allows for the exchange and storage of calendar data, such as events, to-do lists, and journal entries. The format is text-based and human-readable, though often processed by software.

CalDAV, on the other hand, is a calendar access protocol that works over HTTP. It is an open standard developed by the Internet Engineering Task Force (IETF). CalDAV enables clients to access calendar information on a remote web server. It defines how calendar data, typically in the iCalendar format, is organized, synchronized, and managed. Essentially, CalDAV allows users to access and manage their calendars across multiple devices and applications by communicating with a central server.

When these two terms are combined into "ICSCalDAV," it signifies the use of CalDAV to interact with calendar data that is structured and formatted according to the iCalendar standard. This combination is fundamental to how many modern calendar applications and services function, enabling features like shared calendars, synchronization between devices (such as smartphones, tablets, and computers), and the ability to invite others to events. Many popular calendar services and software clients utilize CalDAV and iCalendar to provide a seamless calendar management experience.
