You have the option of subscribing to the University's holiday calendar. Subscribing is a one-time process - the holiday calendar will automatically update each year. Note that Outlook 2016/2011 for macOS does not have the functionality to let you subscribe to an Internet calendar. If you use a Mac and want to subscribe to the University's holiday calendar, you should do so through OWA. The calendar will then show up in Outlook 2016/2011 for macOS.
