Learn what to do if your iCloud Contacts, Calendars, or Reminders aren't appearing on all the devices that you use with iCloud.
Things to check first
Check the system status of iCloud Contacts, Calendars or Reminders for services outages or connection issues.
If a reminder isn't appearing on some of your devices, make sure your iPhone and iPad have the latest version of iOS or iPadOS, or that your Mac has the latest version of macOS.
Make sure you're signed in to iCloud with the same Apple ID on all of your devices. Then check you've turned on Contacts, Calendars and Reminders in your iCloud settings.
Check that the date and time settings on your device are correct for your current location.
If you use iCloud for Windows to sync your Contacts and Calendar with Outlook on your PC, make sure you’ve updated to the latest version of Windows. Then follow these steps to sign out and sign back in again.

If your information is in a third-party account, like Google or Yahoo, you can change your default account to iCloud.
