Google Calendar Pricing & Plans

To share a Google Calendar, you must log into calendar.google.com on a computer, as sharing permissions cannot be configured from the mobile app. From the left sidebar, hover over the calendar you want to share under the 'My calendars' section, click the three-dot icon, and select 'Settings and sharing.' Under 'Share with specific people or groups,' you can click '+ Add people and groups' to add their email addresses and assign their specific access permissions before clicking send.
