How do I create a shared Google Calendar for my team?

To have a team calendar, one person should create a new calendar and add the rest of the team with either "Make changes & manage sharing" access or "Make changes to events" access. Learn more about sharing calendars. 

Note: Unfortunately, there is no ability to send calendar invites from this shared calendar. The event can be created on the shared calendar, but the invitation will have to come from someone (not from the calendar itself), usually whoever created the event or whoever added guests to the event.
