What is iCalendar and iCal
People get confused between iCalendar, iCal and iCloud Calendar. So let's talk about it.
iCalendar is a media type which allows users to exchange calendaring and scheduling information such as meetings, to-dos etc. Files formatted according to the specification typically have an extension of .ics or .ical.
