Method 5: Check the Date and Time on Synced Devices

You might have noticed that when your Date and Time settings are not in order, you can’t access most of the websites. This is because it’s one of the most fundamental pieces of information that tells a lot about your location and time zone.

Syncing your Calendar on all the devices would require you to keep all of your devices updated with the latest date and time settings, otherwise, you won’t be able to access your Calendar data from the synced devices.

It is recommended that you keep your Date & Time settings toggled on for Set Automatically which saves you from extra hassle. Here’s how to do it.

  • Go to Settings >> General.
  • Tap Date & Time.
