To sync iPhone calendar, go to Settings > Apps > Calendar > Calendar Accounts, then tap Add Account and choose a provider. This process connects your existing accounts, iCloud, Google, or Microsoft Exchange, so your events appear in the iPhone Calendar app.
How to sync iPhone calendar accounts
The correct path on current iPhone software is Settings > Apps > Calendar > Calendar Accounts. From there, tap Add Account and select your provider from the options: iCloud, Google, Microsoft Exchange, or Other (for CalDAV accounts). For CalDAV accounts, choose 'Other' when adding an account. Enter your account credentials and turn on Calendars to sync only calendar data.
Sync Google Calendar to your iPhone
- Open Settings > Calendar > Accounts > Add Account > Google.
- Enter your Google email and password.
- On the account screen, turn off any services you do not want to sync (such as Mail or Contacts) so only Calendars is enabled.
- Tap Save.
If you use two-step verification on an older operating system, you may need an app password instead of your regular password to complete the setup. For Google accounts using two-step verification on older operating systems, you may need an app password instead of your regular password.
Sync iCloud Calendar on iPhone
- Go to Settings > [your name] > iCloud.
- On iOS 17 or later, tap See All (or Show All), tap iCloud Calendar, then turn on Use on this iPhone. For iCloud Calendar, the toggle is 'Use on this iPhone' on iOS 17+ and 'Calendars' on iOS 16.
- On iOS 16, tap Show All, then turn on Calendars.
This syncs your iCloud events to the Calendar app automatically.
Verify your calendar is syncing
After adding an account, open the Calendar app. Your events should appear there. For existing accounts, go to Settings > Apps > Calendar > Calendar Accounts, tap the account, and confirm that Calendars is toggled on.
Use the Google Calendar app instead
If you prefer Google’s dedicated interface, install Google Calendar from the App Store, sign in with your Google Account, and your events sync to that app. This is a separate option from the iPhone’s built-in Calendar app and gives you Google’s own layout and features. The Google Calendar app route is a separate option from the iPhone's built-in Calendar app and gives you Google's own layout and features.
Troubleshooting calendar sync problems
- Verify the account was added in the correct path: Settings > Apps > Calendar > Calendar Accounts.
- Confirm Calendars is toggled on for that account.
- For Google accounts with two-step verification on older operating systems, use an app password instead of your regular password.
If you manage a large number of events or need to keep your phone photos and media organized separately, syncing only calendar data, rather than all account services, helps avoid clutter and keeps your focus on your schedule.
Frequently Asked Questions
Does deleting an event on iPhone remove it from other devices?
Yes. When you delete an event from a synced calendar on your iPhone, the change is pushed to the server (iCloud, Google, or Exchange) and then to all other devices connected to that account. The event is removed everywhere.
How does real-time syncing work with an internet connection?
Your iPhone syncs calendar changes almost immediately whenever it has an active internet connection, either Wi-Fi or cellular data. Changes you make on another device appear on your iPhone within seconds, as long as both are online.
Can non-Apple devices sync with iPhone calendars?
Yes. Non-Apple devices can sync with the same calendar account you use on your iPhone. For example, a Windows PC or Android phone can access Google Calendar events, and any CalDAV-compatible client can sync with an iCloud calendar using Apple’s published server settings.
