Internet Calendars

Internet Calendars are calendars that are shared through the Internet [1]. These calendars are based upon a global Internet standard that allows calendar information to be exchanged between people regardless of the application that is used to create or view the information. Internet Calendars use the iCalendar format (not to be confused with Apple's iCal) and the .ics file name extension.

There are two types of Internet Calendars, Calendar Snapshots and Internet Calendar Subscriptions:

  • a Calendar Snapshot is sent to you in an email message in the iCalendar format. It is a static calendar that can be updated only after the calendar owner sends you a new Calendar Snapshot.

    These kind of calendars are usually NOT used by official bodies at the EUI.
  • an Internet Calendar Subscription is a calendar that you open and view, for example, either as a webpage or directly in Outlook as well as many other compatible applications or platform (for example iOS or Google Calendar). However, unlike a Calendar Snapshot, Internet Calendar Subscriptions are updated automatically thus dynamic.

    Subscribing to a calendar may be as easy as a click on a link to download the calendar, or someone can send you a link to the Internet Calendar Subscription in an email message. This link is an Internet web address that begins with webcal:// and ends with a file name that has the .ics file extension.

    The following internet calendars are currently available for subscription at the EUI:
