Getting an iCal link
To find the iCal URL for a particular calendar, select the Feeds icon near the top-right corner of a calendar.
Note: If this icon is not visbile, then the calendar displayed on the webpage cannot be added subscribed to. Additionally, these icons may appear in different colors based on the campuses webpage you are on.
In the Calendar Feeds window that pops up, hover over the green ICAL button and select Get Standard iCal URL.
If you perform this step on your iOS device, then you can long-press this URL to Select All and copy it to the clipboard. If you cannot perform this step on your device, obtain the link on your computer, email or text the URL to your mobile device, and then copy the URL on your device.
In either case, you should end up with the iCal feed URL on your clipboard.
Adding an iCal subscription to your device
Once you have copied the feed URL, add it to your mobile device by following the instructions from Apple.
