Introduction
The iCal4j project is a collection of Open Source Java libraries providing support for the iCalendar specifications (RFCs).
The core iCal4j library provides an implementation of the iCalendar specifications that are designed to facilitate interoperability between calendaring and scheduling software systems.
iCalendar provides a common data format used to store scheduling information such as events, appointments, to-do lists, etc. Most calendaring tools include some level of support for the iCalendar standard.
