Did not uninstall. Long pressed calendar until all apps started wiggling. Tapped the small x and it says "removing this app from your home screen will not delete your calendars or calendar data". But the app icon is gone. How do I retrieve it? New to iPhone, had Androids my whole life. A lot of adjusting.
Yes, that removed the Calendar app. Your calendars are still linked to the phone in Settings>Calendar. If you re-install the preinstalled app or a third party calendar app, you will see all your appointments.
If you don't want to see all the apps on the screen, put them in folders. Press and hold until the apps start to wiggle. Drag one over top of the other and a folder will be created. Drag all the apps into that folder.
