10 Tech How-To

Add Location to World Clock on iPhone

Guide 10-29341 · Updated · Step by step

This guide shows you how to add a city or location to the World Clock in the iPhone’s Clock app, so you can quickly see the current time in different time zones. You’ll need your iPhone with iOS 14 or later (the steps are nearly identical on older versions). No other setup is required.

What You’ll Need

  • An iPhone with the Clock app (pre-installed on all iPhones).
  • An active internet connection is helpful but not required—the time zone data is stored on the device.
  • Optional: Turn on Location Services for the Clock app if you want to add your current location automatically (Settings > Privacy & Security > Location Services > Clock > While Using the App).

Step-by-Step

  1. Open the Clock app on your iPhone. It’s a white app with a black clock icon, usually on your Home Screen or in the Utilities folder.
  2. Tap the “World Clock” tab at the bottom of the screen. It’s the second icon from the left, showing a small globe.
  3. Tap the “+” button in the top-right corner of the World Clock screen. This opens the search interface.
  4. Type the name of the city or location in the search bar. You can type a city name (e.g., “Tokyo”), a country (e.g., “Japan”), or even a major airport code (e.g., “NRT”).
  5. Select the correct match from the list that appears below. The list will show cities and regions with their country names. Tap the one you want—it will immediately be added to your World Clock list.
  6. Repeat for any other locations you want to add. You can add as many as you like.
  7. Reorder or remove locations if needed: In the World Clock list, tap “Edit” in the top-left corner. Then drag the three-line handle on the right to reorder, or tap the red minus button to delete. Tap “Done” when finished.

Common Mistakes

  • Typing a country instead of a city: If you type “United States,” you’ll get a generic entry that may not represent the time zone you want. Always type a specific city (e.g., “New York”) or a major city in that time zone.
  • Choosing the wrong city with the same name: Many cities share names (e.g., Portland, Oregon vs. Portland, Maine). Check the country or state listed under each match to pick the right one.
  • Adding a location that doesn’t observe daylight saving time: The Clock app automatically adjusts for DST, but if you pick a city that doesn’t observe it (e.g., Phoenix, Arizona), the time will still be correct—just don’t be surprised it doesn’t change in March/November.
  • Not using the search bar: Some users try to scroll through the list of all cities, which can be overwhelming. Always use the search feature for speed and accuracy.

Tips

  • Add your current location automatically: In the World Clock tab, tap the location arrow (top-right) to add your current city based on GPS. This is handy when traveling.
  • Use city names, not time zone abbreviations: Search for “London” rather than “GMT”—the latter may not be recognized.
  • Add multiple cities in the same time zone: If you work with colleagues in different parts of the same country, add each city individually to avoid confusion.
  • Use the World Clock widget: After adding locations, you can add a Widget to your Home Screen to see them at a glance. Press and hold the Home Screen, tap “+”, search for “Clock,” and choose the World Clock widget.
  • Check the time difference quickly: In the World Clock list, the time difference from your current location is shown in parentheses (e.g., “Today, +9 hours”).

Troubleshooting

  • No search results appear: Make sure you have an internet connection, as the search uses Apple’s servers. If offline, try again later or type a more common city name.
  • The location I want isn’t in the list: Very small towns may not be available. Use the nearest major city or a regional capital instead.
  • The time is wrong for a location: Check that your iPhone’s time zone is set correctly (Settings > General > Date & Time > Set Automatically). If you manually set the time zone, it might override the World Clock’s automatic updates.
  • I added a location, but it disappeared: This can happen if you accidentally tapped the red minus button while editing. Re-add it using the steps above.
  • The World Clock tab is missing: If you don’t see the World Clock tab, you might be in a different Clock app view (e.g., Alarm). Tap the “World Clock” icon at the bottom—it’s the second from the left.
  • Location Services won’t turn on for Clock: Go to Settings > Privacy & Security > Location Services > Clock and select “While Using the App.” If it’s grayed out, restart your iPhone and try again.

Frequently Asked Questions

Can I add a location that doesn’t have a city, like a time zone?

Yes, you can search for a time zone name (e.g., “Central European Time”) or a major city in that zone. The Clock app will show the current time for that zone.

How many locations can I add to World Clock?

There’s no official limit, but practical limits of memory and interface mean you can add dozens. Most users add 10–20 without any issue.

Will the World Clock automatically adjust for daylight saving time?

Yes, the Clock app automatically adjusts for DST based on the location’s rules, as long as your iPhone’s date and time are set correctly.

Can I add a location using its airport code?

Yes, you can type an IATA airport code (e.g., “JFK” for New York, “LHR” for London) and the corresponding city will appear.

Why does the World Clock show a different time than my computer?

Your computer may be set to a different time zone or have incorrect DST settings. Ensure both devices are set to “Set Automatically” for time zone.

Can I see the time in a location without adding it to World Clock?

Yes, you can use the Clock app’s “World Clock” search to view a city’s time temporarily, but it won’t be saved unless you tap the “+” to add it.
