The present invention discloses a solution for adding syndication feeds to calendar data exchange enabled programs, such as programs conforming to the iCalendar (iCal) standard. Default syndication feed links can be established by a publisher of iCalendar data. Subscribers of iCalendar data can replace default syndication feeds with feeds from other sources and/or add their own syndication feeds to a program that supports iCalendar data. Information obtained from the syndication feeds can be stored in a calendar entry indexed fashion, so that users accessing a iCalendar program can view information obtained from the syndication feeds as well as information related to an iCalendar subscription.
