Webcal is a uniform resource identifier (URI) scheme for accessing iCalendar files. WebCal allows you to create and maintain an interactive events calendar or scheduling system on a Web site or app.^{[1][dead link]}

The webcal scheme was devised for use with the Apple iCal application and has become a common de facto standard for accessing iCalendar formatted files via WebDAV, usually using GET method.^{[citation needed]} It is not an official URI scheme, such as http and ftp, as registered with IANA. As of 23 September 2012^[update], the webcal scheme has provisional status with IANA.^[2] The Webcal protocol prefix is used to trigger an external protocol handler which is passed the URL of the .ics file rather than being passed the downloaded contents of the file, in much the same way feed is sometimes used to trigger external RSS readers. The idea is that with this protocol prefix the target file should be subscribed to rather than imported into the calendar application as would happen with a simple download.
