The quickest way to change your iPhone's date

Open Settings, tap General, then tap Date & Time. Toggle off Set Automatically if it is on. Now you can tap the date and time fields to change them manually. When you are done, toggle Set Automatically back on if you want your phone to sync with your carrier's time again.

Most of the time, your iPhone sets the date and time on its own using your cellular network or Wi-Fi connection. You only need to change it manually if your phone is showing the wrong time, or if you are testing something that depends on the date—like checking whether a subscription has expired or whether a scheduled event will trigger.

Key Takeaways

  • The date and time settings are in Settings > General > Date & Time, and you must turn off Set Automatically before you can edit them manually.
  • Your iPhone normally syncs the correct time from your carrier or Wi-Fi network, so manual changes are rarely needed.
  • If your phone shows the wrong time after toggling Set Automatically back on, restart your iPhone or check that your location services are enabled.
  • Changing the date on your iPhone does not affect your Apple ID, iCloud backups, or any data stored in the cloud.

Why your iPhone might show the wrong date or time

If your phone is off by a few minutes or hours, the most common cause is that Set Automatically is turned off. This setting tells your iPhone to pull the correct time from your carrier's network or from a time server over Wi-Fi. When it is off, your phone relies on its internal clock, which can drift.

A second common cause is that your iPhone is in Airplane Mode or has lost its connection to the network. Without a signal, your phone cannot fetch the correct time. Turning off Airplane Mode or reconnecting to Wi-Fi usually fixes this within a few seconds.

If you recently traveled across time zones, your phone should update automatically if Set Automatically is on. If it does not, try restarting your iPhone: hold down the power button until you see the power-off slider, swipe to turn it off, wait a few seconds, then hold the power button again until the Apple logo appears.

Changing the date and time manually, step by step

Open the Settings app on your home screen. Scroll down and tap General. Tap Date & Time.

You will see a toggle labeled Set Automatically. If it is green (on), tap it to turn it off. The toggle will turn gray. Now you can tap the date field and the time field to edit them.

Tap the date field. A date picker will appear. Scroll up or down to select the month, day, and year you want. Tap the time field and use the same method to set the hours and minutes. When you are finished, tap Back or swipe back to return to the Date & Time screen.

If you want your phone to sync with the network time again, toggle Set Automatically back on. Your phone will fetch the correct time within a few seconds.

When to turn off Set Automatically and when to leave it on

Leave Set Automatically on in almost all situations. This is the default setting, and it keeps your phone in sync with the actual time without any work from you. Your phone will update automatically when you cross time zones, and it will account for daylight saving time changes.

Turn it off only if you are testing something that depends on the date or time—for example, checking whether an app will send a notification on a specific date, or whether a trial subscription will expire. Once you are done testing, turn it back on.

Some people turn it off temporarily if they are in an area with poor network coverage and their phone keeps jumping to the wrong time. In that case, set the time manually and leave Set Automatically off until you have a stable connection again.

What happens to your data when you change the date

Changing your iPhone's date does not delete anything or break your backups. Your photos, messages, and app data are stored with their original timestamps, so changing the system date does not alter them. If you back up to iCloud, that backup is tied to your Apple ID, not to your phone's clock.

However, some apps may behave unexpectedly if the date is very far in the past or future. For example, a banking app might refuse to log in if your phone thinks it is 2050. A fitness app might not record workouts correctly if the date is wrong. These issues go away as soon as you set the date back to the correct time.

Fixing a date that is still wrong after toggling Set Automatically back on

If you turn Set Automatically back on and your phone still shows the wrong time, restart your iPhone. Hold the power button until the power-off slider appears, swipe to turn it off, wait 10 seconds, then hold the power button again until you see the Apple logo.

If the time is still wrong after a restart, check that you have a network connection. If you are on Wi-Fi, try disconnecting and reconnecting. If you are on cellular, make sure Airplane Mode is off. Your phone should sync within a few seconds of regaining a connection.

If the problem persists, check that Location Services is turned on. Some time servers use your location to determine the correct time zone. Go to Settings > Privacy > Location Services and make sure the toggle is on.

Frequently Asked Questions

Does changing the date on my iPhone affect my iCloud backup?

No. Your iCloud backup is stored on Apple's servers and is tied to your Apple ID, not to your phone's clock. Changing the date on your iPhone does not affect whether your backup works or what is stored in it.

Will changing the date break my apps or subscriptions?

Most apps will work fine, but some may behave strangely if the date is very far in the past or future. Banking apps, for example, might refuse to log in. Once you set the date back to the correct time, the app will work normally again.

Can I change just the time without changing the date?

Yes. Turn off Set Automatically, then tap only the time field and adjust the hours and minutes. Leave the date field alone. When you are done, toggle Set Automatically back on.

What if my phone keeps changing the date back after I set it manually?

This means Set Automatically is still on. Go back to Settings > General > Date & Time and make sure the toggle is off before you change the date. If it is already off and the date keeps changing, restart your iPhone.

Does my iPhone need to be connected to Wi-Fi to set the time automatically?

No. Your iPhone can sync the time over cellular network as well. However, it needs either a Wi-Fi or cellular connection to do so. If you are in Airplane Mode or have no signal, Set Automatically cannot work.
