Google Calendars can be shared with others giving them various levels of access depending on how you share the calendar.

Restrictions on Sharing @stonybrook.edu Google Calendars

You can share your @stonybrook.edu Google calendars within Stony Brook University and outside. However, there are some restrictions for sharing your primary Stony Brook Google Calendar outside of the Stony Brook domain. 

Primary Calendars

• You can share your primary work calendar (the one with your name on it) with other @stonybrook.edu Google email addresses at any level of sharing. So you can give others at Stony Brook access to view or edit your events, for example.
• You can share your primary calendars with those outside the @stonybrook.edu Google domain only at the free/busy level. That is, if you want to share your first.last@stonybrook.edu Google Calendar with a gmail account, the gmail account will only be able to see when your calendar is busy, not any specific events.
• If you want to view a personal gmail calendar and your primary first.last@stonybrook.edu calendar on the same screen, share your personal calendar with your @stonybrook.edu account.  We cannot share details of our primary work calendars with accounts outside of Stony Brook (only free/busy level access).

Secondary Calendars

• Secondary calendars that you've created (e.g., a project calendar) can be shared within or outside the @stonybrook.edu Google domain at any level. So you can share a Google Calendar you created with a gmail account so the gmail account can see all events details or even edit events.
