When your iPhone calendar events disappear, there's no need to panic. Here are some basic yet effective solutions you can try one by one to recover your calendar content.

Fix 1. Restart iPhone

Prolonged device usage or temporary system glitches may cause all events on the iPhone calendar to disappear. In this case, the simplest and most effective action is to restart your iPhone, as it can clear the cache and reload system components.

To restart the iPhone, follow the steps below:

For iPhone X, 11, 12, 13, or newer:

• Press and hold both the "Volume" button and the "Side" button until the power-off slider appears.
• Slide to power off, then wait about 30 seconds for the device to fully shut down.
• To turn it back on, press and hold the "Side" button until the Apple logo shows up.

For iPhone 6, 7, 8, or SE (2nd/3rd gen):

• Press and hold the "Side" button until the power-off slider appears.
• Drag the slider to turn off your device, then wait 30 seconds for it to power down.
• To power it back on, press and hold the "Side" button until the Apple logo appears.

Step 1. Go to "Settings" > [your name] > "iCloud" > "Calendars" to switch it off.

Step 2. Wait for a few seconds and turn it on again on your iPhone to activate it.

Fix 4. Show All Calendar Events

iPhone calendar disappeared after the update? Due to the restoration, upgrade, or reset of your iPhone, some settings on the Calendar app may be changed, which may make calendar events fail to sync to the stock Calendar app on iPhone, like the older events.

Step 1. On your iPhone, go to "Settings" > "Mail, Contacts, Calendars".

Step 2. Scroll down to "CALENDARS" and tap "Sync".

Step 3. Select "All Events" under the Sync page.
