ICS - iCalendar File

What is a ICS file

ICS is a global format for calendar files widely being utilized by various calendar and email programs including Google Calendar, Apple iCal, and Microsoft Outlook. These files enable users to share and publish information directly from their calendars over email or via uploading it to the world wide web. The recipients of such files can thus easily implement them into their own calendars or schedules.

Saved as plain text files, calendar information stored in ICS files comprises the information like the title, start time, end time, and an summary for the calendar event. Cancelling and updating an event is also supported when using the ICS file format.

Here's a small, but not exhaustive list of programs that can open ICS documents:

  • Microsoft Outlook 2013
  • Mozilla Sunbird
  • Microsoft Works
Extension ICS
