All the events from my iPhone calendar suddenly disappeared pl/eng

Start by checking if it's a sync error or if your calendar appointments are missing. You can check this on iCloud, and in Google Calendar. Log in to both places and see if your appointments are still there.

• Check iCloud HERE

(If your appointments in iCloud have been deleted, you can restore them at icloud.com)

• Check Google Calendar HERE

If your appointments are still visible in the online calendars, then there is a synchronization error.

For iCloud:

Check that Calendar is syncing. Go to:

Settings > Apple Account (Your Name) > iCloud > find Calendar in the list and check if it is enabled. If so, try disabling, restarting your iPhone, going back and enabling again. It is not a must, but it is always a good idea to be connected to WiFi.

Also check if the calendar is enabled INSIDE the calendar. Open the calendar app, tap calendars at the bottom - and see if your various calendars have a check mark next to them. If they do not have a check mark, they will not be visible. Tap them to make them visible.

For Google Calendar:

Go to Settings > Apps > Calendar > Calendar Accounts > select your Google account and check if Calendar is enabled. If not, enable. If you were unable to get Google Calendar to sync and you need your appointments urgently, you can download the Google Calendar app as a standalone app. All you have to do is log in and you will be able to see the same things you can online.

• Download the Google Calendar app in the App Store
