In the spring of 2018, OSU is upgrading its event calendar to a new system called Localist. The new system is available at https://events.oregonstate.edu/ and has different options for how the feed widgets display (shown below). One of the differences in Localist is that your individual calendar is termed an "Organization." An event can belong to multiple Organizations, so when entering an event into the system, be sure to select all of the relevant Organizations where the event should appear.
If you would like to have an events calendar added to your web site, Contact the CAS Web Team and we will help you set one up.
As of May 2018: We are in the process of updating each of our current sites to the new calendar system.
