Calendars help you keep track of what youâ€™re doing and when, which is why itâ€™s always been one of the core apps on mobile devices to the latest iPhones and iPads. That why, when iOS launched in 2007, it included a Calendar app. Whether you simply use Calendar by itself, or whether you sync it via iCloud, Google Calendar, Microsoft, or something else, itâ€™s the default way to add and find appointments and events. Below are some useful fixing solutions for problems while you are using calendar on iPhone or iPad.
Google calendar does not show up in the calendars app on your iPhone, iPad, or Mac
If you accepted an invitation from someone to share a Google calendar but arenâ€™t seeing it on your iPhone, iPad, or Mac; it could be due to your Google Sync settings. Google turns sync off by default for new calendars, particularly shared ones. Itâ€™s frustrating, and itâ€™s why you canâ€™t immediately see them on your iPhone, iPad, or Mac even when you can see them online. Luckily itâ€™s also simple to fix â€” once you know how!
Launch Safari or any other web browser on your iPhone, iPad, or Mac.
Go to https://www.google.com/calendar/syncselect.
Sign in (if you arenâ€™t already).
Under Shared Calendars, make sure all the boxes are checked for the calendars you want to see on iPhone, iPad, and Mac.
