If you are using the YaleSites Calendar feature, site visitors might want to add your events to the calendar on their phone, google calendar etc.  As the site administrator you might want to import your events from another calendar such as a Google Calendar. In order for this functionality to be available as part of your Calendar Feature, you must create an iCal (or iCalendar) feed and attach it to your calendar or the individual events on your calendar.

iCal is an Internet file format that allows you to do just that, share events on your calendar between various calendar products used by your site visitors. There are 2 main ways you might want to share information on YaleSites Calendar:

• Importing events into the calendar from other calendars - Google Calendar, etc.
• Exporting events from your calendar to other calendars on various devices – phone, tablet, etc.

This tutorial will provide you with instructions for adding the iCal feed to your calendar or individual event so site visitors can import your events to their calendars, and importing events from external calendars, in this case a Google Calendar.

Important Note: if you are importing your events from the Yale Institutional Calendar (Bedeworks) you can use the pre-built feature. Instructions can be found here.
