Q: Why do I show up as available on Google Calendar on a Simmons holiday? A: The Simmons Holidays calendar in Google Calendar is a separate calendar from the personal one that is automatically shared (showing only free/busy time) with then entire Simmons community. In order to block the Simmons holidays in your personal calendar you can copy all the meetings listed in the Simmons Holidays calendar to your calendar, marking the events as busy.
