If you have side by side calendars enabled (for Day View) in Google Calendar, you'll see people's main calendars and Resource calendars in separate columns. Any calendars you or a colleague created will display in the first column with your main calendar. 

• The first column will show your main First.Last@stonybrook.edu calendar AND any calendars you/coworker created (secondary calendars)
• Additional columns will separately display others' first.last@stonybrook.edu calendars (i.e., other primary calendars) and SBU Resource calendars
