The easiest way to sync calendars between an iPhone and an iPad is iCloud. Sign in to the same Apple Account on both devices, then turn on iCloud Calendar on each one: open Settings, tap your name, tap iCloud, tap See All, tap iCloud Calendar, and turn on Use on this iPhone (or Use on this iPad). New and edited events then appear on both devices automatically, over Wi-Fi or cellular, with no cable needed.
If your events live in Google Calendar, Outlook, or another service instead, add that same account to the Calendar app on both devices and turn on its calendars. This guide covers both setups, how to handle shared family calendars, and what to check when events don’t show up.
Quick Answer
- On both devices, check that you’re signed in to the same Apple Account (tap your name at the top of Settings).
- On the iPhone, go to Settings > your name > iCloud > See All > iCloud Calendar and turn on Use on this iPhone.
- Do the same on the iPad and turn on Use on this iPad.
- Open the Calendar app on each device, tap Calendars, and make sure your iCloud calendars are selected.
- Set iCloud as the default calendar so new events sync: Settings > Apps > Calendar > Default Calendar.
- For Google or Outlook calendars, add the account and turn on Calendars on both devices.

Before You Start
These steps apply to iPhones and iPads with recent versions of iOS and iPadOS, as of September 2026. Apple’s labels changed slightly over the years: on iOS 17 and later you’ll see See All and iCloud Calendar, while iOS 16 shows Show All and a Calendars switch. Where the steps differ, both versions are noted.
What you need:
- The same Apple Account on both devices. Your Apple Account (formerly called Apple ID) is the email and password you use for iCloud and the App Store. iCloud only syncs calendars between devices signed in to the same account.
- An internet connection on both devices. Sync happens through iCloud’s servers, not directly between the devices.
- Up-to-date software. Apple recommends the latest iOS or iPadOS when sync isn’t working. Check in Settings > General > Software Update.
A quick explanation of terms: a calendar account is where your events are stored (iCloud, Google, Outlook, and so on). The Calendar app on your iPhone and iPad is just a window into those accounts. Syncing works when both devices look at the same account. If an event is saved in an account only one device uses, the other device can’t show it.
If you haven’t set up iCloud on one of the devices yet, start with our guide to signing in to iCloud on your iPhone or iPad.
Method 1: Turn On iCloud Calendar on the iPhone
Apple’s steps for this are in its guide to setting up iCloud for Calendar on all your devices.
- Open the Settings app.
- Tap your name at the top. Expected result: your Apple Account page opens. Note the email address shown; you’ll compare it on the iPad.
- Tap iCloud.
- Tap See All (on some versions, Show All) to see every app that can use iCloud.
- Tap iCloud Calendar.
- Turn on Use on this iPhone. On iOS 16, simply turn on the Calendars switch instead.
- If you’re asked whether to merge calendars already on the iPhone with iCloud, choose to merge if you want those existing events to sync too.
Expected result: your iCloud calendars appear in the Calendar app. The first sync can take a few minutes if you have many events.
Turn On iCloud Calendar on the iPad
Repeat the same steps on the iPad. The only difference is the switch name.
- Open Settings on the iPad and tap your name.
- Confirm that the email address matches the one on your iPhone. If it doesn’t, see the section on different Apple Accounts before going further.
- Tap iCloud > See All (or Show All) > iCloud Calendar.
- Turn on Use on this iPad (or the Calendars switch on iPadOS 16).
- Open the Calendar app and wait a minute. Expected result: the events from your iPhone appear.
To test the sync, create an event on the iPhone called “Sync test”, check that it’s saved to an iCloud calendar, and look for it on the iPad a minute later. Delete it on the iPad and confirm it disappears from the iPhone.
Check Which Calendars Show and Where New Events Go
Turning on iCloud Calendar is only half the job. Two settings decide whether you actually see the same events on both devices.
Show all iCloud calendars
- Open the Calendar app.
- Tap Calendars at the bottom of the screen.
- Under the iCloud section, make sure every calendar you want to see has a checkmark.
- Tap Done.
Do this on both devices. A calendar that’s hidden on the iPad is still synced; it’s just not displayed.
Set iCloud as the default calendar
New events go to your default calendar unless you pick another one when you create them. If the default is a calendar stored only on the device (often labeled “On My iPhone” or “On My iPad”), those events won’t reach the other device.
- Go to Settings > Apps > Calendar. On older iOS versions, go to Settings > Calendar.
- Tap Default Calendar.
- Choose a calendar under iCloud.
Events you already created in a local calendar don’t move by themselves. You can move one by opening the event, tapping Edit, tapping Calendar, and choosing an iCloud calendar. Apple’s Community forums note there’s no bulk move on iPhone, so this is done one event at a time.
Method 2: Sync Google, Outlook, or Other Calendars
If your events live in a Google or Microsoft account, you don’t need iCloud for them. Add the same account to both devices, and each one syncs directly with that service. Google’s help page on syncing Google Calendar with Apple Calendar describes these steps.
Add the account on the iPhone
- Open Settings and go to the Calendar settings. On current iOS versions, that’s Settings > Apps > Calendar; on older versions, Settings > Calendar.
- Tap Calendar Accounts (labeled Accounts on some versions).
- Tap Add Account and choose Google, Microsoft Exchange, Outlook.com, or another provider.
- Sign in with that account’s email and password, and approve any verification prompt from the provider.
- On the next screen, make sure Calendars is turned on. You can turn off Mail, Contacts, or other items if you only want calendar sync.
If the account is already on your iPhone for email, you don’t need to add it again. Open its entry in the accounts list and turn on Calendars.
Repeat on the iPad
Add the same account on the iPad and turn on Calendars. Expected result: the account’s calendars appear in the Calendar app on both devices under the account’s name.
Google notes a few limits when you use Google Calendar through Apple’s Calendar app, including no email notifications for events and no way to create new Google calendars from the app. If you rely on those features, use the Google Calendar app itself; our guide on making Google Calendar the default on iPhone explains how to set it up.
Choose how far back events sync
For some account types, the Calendar settings include a Sync option that controls how many past events are downloaded. If older events are missing on one device, check that this is set the same on both, for example to All Events. The option may not appear for every account type.
If the iPad Uses a Different Apple Account
Families often share an iPad signed in to one person’s Apple Account while each person has their own iPhone. In that case, turning on iCloud Calendar won’t merge the calendars, because they belong to different accounts. You have two good options:
- Share a calendar. Create a calendar such as “Family” in iCloud and share it with the other person’s Apple Account email address, with permission to view or edit. They accept the invitation, and it appears on their devices. In the Calendar app, tap Calendars, tap the info button next to the calendar, and look for the option to add a person. On iCloud.com, Apple documents the same sharing with Allow editing or read-only access.
- Switch accounts. If the iPad is really yours, sign out of the other Apple Account and sign in with yours. Before signing out, make sure any data on the iPad that belongs to the other person is backed up in their iCloud.
Don’t sign in to someone else’s Apple Account on your iPhone just to see their calendar. Sharing keeps each person’s messages, photos, and passwords private.
Which Method Should You Use?
| Your situation | Best approach |
|---|---|
| You use Apple’s Calendar app and one Apple Account on both devices | iCloud Calendar on both devices |
| Your events are in Gmail or Google Workspace | Add the Google account on both devices, or use the Google Calendar app |
| Your work calendar is in Outlook or Exchange | Add the Microsoft account on both devices (your employer may require the Outlook app) |
| The iPhone and iPad belong to different people | Share an iCloud calendar between the two accounts |
| You also need calendars on a Windows PC or the web | iCloud, which also works at icloud.com/calendar |
You can use more than one method at the same time. Many people keep personal events in iCloud and work events in Outlook, with both accounts added to both devices.
Troubleshooting
Apple’s support article If your iCloud Contacts, Calendars, or Reminders won’t sync lists the official checks. Here they are in a practical order.
Events from the iPhone don’t appear on the iPad
- Confirm both devices show the same Apple Account email under Settings > your name.
- Check that the event was saved to an iCloud calendar, not a local “On My iPhone” calendar.
- In the Calendar app, tap Calendars and make sure all iCloud calendars are selected.
- Pull down on the calendar list to refresh it.
Sync worked before but has stopped
- Check Apple’s System Status page for an iCloud Calendar outage.
- Close the Calendar app, wait about a minute, and open it again.
- Make sure the date and time are correct on both devices; Settings > General > Date & Time with automatic time turned on is the safest choice.
- Restart both devices.
Turning iCloud Calendar off and on
If nothing else works, you can turn off iCloud Calendar on the device that’s out of date and then turn it back on. Before you do, make sure your events are visible at icloud.com/calendar, which confirms they’re safely stored in iCloud. When you turn it off, the device may ask whether to keep a copy on the device or delete it; the copy stored in iCloud isn’t affected.
Google or Outlook events are missing on one device
Open the account in the Calendar accounts settings and make sure Calendars is on. If the account asks you to sign in again, do so, since a changed password stops sync. For Google, check that the specific calendar is shown in the Calendar app’s Calendars list.
Duplicate events
Duplicates usually mean the same calendar is coming from two accounts, for example a Google calendar that was also imported into iCloud. Hide or remove one source rather than deleting events one by one. Our guide on deleting calendar events on iPhone helps with the leftovers.
Frequently Asked Questions
Do I need a cable or a computer to sync calendars?
No. iCloud and online accounts like Google sync over the internet. Both devices just need to be signed in and connected.
Why does my iPad show different events than my iPhone?
The devices are either using different accounts, showing different calendars, or saving new events to a local calendar. Check the Apple Account, the Calendars list, and the default calendar on both.
How long does calendar sync take?
Changes usually appear within a minute or so when both devices are online. The first sync after turning on iCloud Calendar can take longer if you have many events.
Will turning on iCloud Calendar delete events already on my iPhone?
No. If you’re asked, choose to merge so existing events upload to iCloud. Only events in iCloud (or another online account) sync to the iPad.
Can two people with different Apple Accounts share a calendar?
Yes. Share an iCloud calendar with the other person’s Apple Account email address, and give them view or edit permission.
Can I see my iPhone calendar on a Windows computer?
Yes. Sign in at icloud.com/calendar in a browser, or use iCloud for Windows to add your iCloud calendars to Outlook.
