If your phone shows the wrong time after the clock change, check automatic date and time and the selected time zone first. On iPhone, open Settings > General > Date & Time. On Android, search Settings for Date and time. Enable the automatic options available on your phone, then check that the time zone matches your location.
For US readers: daylight saving time ends on Sunday, November 1, 2026, in areas that observe it. At 2:00 a.m. local time, clocks return to 1:00 a.m. Hawaii and most of Arizona do not make this change. Other countries use different dates or do not observe daylight saving. See NIST’s daylight saving time rules.
First, check which clock is wrong
| What you see | Check first |
|---|---|
| The phone is exactly one hour ahead or behind | The selected time zone and local daylight saving rules. |
| The time is wrong by several minutes, or the date is wrong | Automatic time, network access and any manual settings. |
| The phone is right, but a calendar event is wrong | The event’s time zone and the calendar app’s display settings. |
| The phone is right, but the car or watch is wrong | That device’s own clock and synchronization settings. |
Compare the phone with a reliable clock for your actual city. A World Clock entry for another city is not the same as the phone’s main time zone. If Android Auto is correct but the dashboard is not, follow our guide to fixing a car clock that did not update.
Fix the wrong time on iPhone
- Connect to the internet and check for an iOS update.
- Open Settings > General > Date & Time and enable Set Automatically, or the equivalent automatic controls shown on your version.
- For location-based time-zone detection, check Settings > Privacy & Security > Location Services > System Services > Setting Time Zone.
- If iOS asks you to restart after a time-zone update, restart the iPhone and any paired Apple Watch.
Apple‘s date and time troubleshooting guide explains these controls. Names and availability can vary by software version, carrier and region.
Fix the wrong time on Android
Search the phone’s Settings for Date and time. Turn on automatic date/time and automatic time-zone detection where supported. On phones using Google’s Clock app, you can also open Clock > More > Settings > Change date and time.
If your device offers location-based time-zone detection, check its location setting. Google notes that some devices need location to determine the zone, and some do not support automatic zone selection. See Google’s time and time-zone settings guide.
Samsung Galaxy
Open Settings > General management > Date and time. Check Automatic date and time and Automatic time zone. Samsung says these settings use mobile-network information. If they do not update, check your connection and the selected zone. Menu options differ on some tablets; Samsung’s instructions cover automatic and manual setup.
Xiaomi, Redmi and POCO
On supported models, open Settings > Additional settings > Date & time. Enable the automatic time and time-zone options available. Labels vary across MIUI and HyperOS versions. Xiaomi documents automatic time and automatic time-zone selection separately.
Choose the region and time zone that match where you are. Selecting Spain is not a general fix for users in other countries.
Automatic time is on, but the clock is still wrong
Check the displayed time zone before changing the hour yourself. An incorrect zone can leave the phone an hour out even when its time source is working.
If the connection is unreliable, reconnect and restart the phone, then check for a system update. Xiaomi also suggests briefly enabling and disabling airplane mode for occasional time-sync problems. This can interrupt calls and mobile connectivity; see its time synchronization advice.
If only a meeting is wrong, inspect that event instead. Google Calendar explains how event time zones and changes to local rules can affect the time you see.
Set the time manually if automatic setup fails
On iPhone, return to Date & Time and disable the relevant automatic setting. On Android, open the same settings page and switch off the automatic control for the value you need to change. Select the correct city or time zone, date and time.
Recheck the clock after the next time change or trip, and restore automatic setup when the problem is resolved. A manually selected city-based zone may still apply daylight saving rules; turning off automatic zone detection does not necessarily disable those rules.
Check your alarms after the clock change
Once the phone’s clock is correct, open your alarm app and confirm the next alarm’s time, AM/PM, repeat days and sound. Keep the phone powered on and charged, and try a test alarm. For an important wake-up, use an independent backup.
On iPhone, check a Sleep Schedule wake-up alarm separately from a regular Clock alarm. Apple explains the difference in its alarm guide. On Android, check alarm volume, sound, notifications and whether Do Not Disturb allows alarms; Google’s alarm troubleshooting steps cover these settings.
Frequently asked questions
Will my phone change the time automatically?
It should when automatic time and the appropriate time zone are configured and supported. Check the displayed time and location after the change rather than assuming every connected device has updated.
Why is Set Automatically greyed out on iPhone?
Apple says Screen Time restrictions, a managed-device profile, carrier support or regional availability can affect this control. Check those restrictions, or ask the device administrator.
Do I need to move my alarm back an hour?
Correct the phone’s clock first, then confirm the local wake-up time you want. Do not compensate for a wrong phone clock by changing only the alarm. Check the app’s next scheduled alarm before relying on it.
Will an alarm at 1:30 a.m. ring twice when clocks go back?
The local 1 a.m. hour repeats in US areas making the November change. Alarm handling can depend on the app and software version, so do not assume a repeated alarm. Check the app’s guidance and use an independent backup if timing matters.
