Learn How to Change Time on Your Devices

Understanding Device Time Settings and Why They Matter

Time settings on your devices affect far more than just knowing what hour it is. When your phone, computer, or tablet displays the wrong time, it can disrupt your entire digital life. Emails may show incorrect timestamps, appointments can appear at the wrong times, and automatic tasks may run when you don't expect them. Your device's time also connects to security features, software updates, and financial transactions. Banks rely on accurate timestamps to process transactions in the correct order. Apps that track your location or monitor your health depend on precise time data. Understanding how time works on your devices gives you control over these functions and helps prevent confusion or errors.

Most modern devices use a network time protocol, which means they can sync with internet time servers to stay accurate. However, you may need to adjust this setting if you travel between time zones, experience a power outage, or if your device's internal clock battery runs low. Learning to manually change the time on your devices is a practical skill that takes only a few minutes to master. Different devices—whether smartphones, computers, or tablets—use slightly different methods, but the underlying principles remain the same. This guide walks through the specific steps for the most common device types you likely own.

Practical Takeaway: Before making time changes, check whether your device is set to update time automatically. This setting, often called "Set automatically" or "Sync with internet time," prevents most time-related issues without any action on your part.

How to Change Time on iPhones and iPads

Apple devices make time adjustment straightforward through the Settings app. To begin, open Settings on your iPhone or iPad and look for the option labeled "General." Once you tap General, scroll down until you find "Date & Time." This section contains all the controls you need to manage your device's time settings. At the top of the Date & Time menu, you'll see a toggle switch that says "Set Automatically." When this toggle is turned on (it appears green), your device pulls the correct time from Apple's network servers and adjusts automatically when you cross time zones. This is the recommended setting for most users.

If you need to set the time manually, first turn off the "Set Automatically" toggle by tapping it. Once disabled, new options appear on your screen. You'll see fields for setting the time and date manually. Tap on "Time Zone" to select your location—this determines which time zone your device displays. The device will show you a list of cities grouped by region. Scroll through and find your location or a city in your same time zone. After selecting your time zone, you can manually adjust the hour and minute if needed by tapping the time display and using the plus and minus buttons that appear. Some devices show a dial you can rotate to set the time, while others use number spinners.

For users who travel frequently, knowing how to switch time zones quickly matters. When you arrive in a new location, simply return to Settings > General > Date & Time and tap the Time Zone field. Your device will likely show a list of suggested cities based on your approximate location. Select the correct time zone for where you are, and your device will update the display immediately. You don't need to manually adjust the hours if you select the right time zone—the device calculates the difference automatically.

Practical Takeaway: Keep "Set Automatically" enabled during normal use. Only disable it if you have a specific reason to display a different time than your actual location uses, such as coordinating with people in another time zone for work purposes.

Changing the Time on Android Phones and Tablets

Android devices offer similar time-setting features, though the exact menu names vary slightly depending on your manufacturer and Android version. Start by opening the Settings app and look for an option called "System," "About phone," or simply "Settings" (the organization differs between Samsung, Google Pixel, OnePlus, and other brands). Once you've entered the main Settings area, search for "Date and time" using the search function at the top of your Settings app. This method works faster than scrolling through multiple menus, especially on devices with many settings options.

When you reach the Date and Time menu, you'll find a toggle labeled "Automatic date and time" or "Use network-provided time." Keeping this enabled ensures your device stays synchronized with your mobile carrier's time servers and adjusts automatically for daylight saving time changes. The second toggle you'll see is "Automatic time zone," which similarly keeps your time zone current based on your location. These two settings working together mean you rarely need to manually adjust anything, even when traveling.

To manually change your time zone on Android, tap on the "Time zone" option below the automatic toggles. This opens a list of available time zones organized alphabetically or by region, depending on your device. Scroll to find your location or the nearest major city in your time zone. Once selected, your device displays the updated time immediately. If you need to manually set the time (not recommended for regular use), disable the "Automatic date and time" toggle first. This reveals options to set the date and time with up-and-down arrows or spinners. Enter the correct month, day, year, hours, and minutes in the fields provided.

Practical Takeaway: If you notice your Android device's time is frequently incorrect despite "Automatic date and time" being enabled, try restarting your device or temporarily disabling and re-enabling the automatic time setting to force a refresh from your network provider.

Adjusting Time on Windows Computers and Laptops

Windows computers handle time settings through the system clock located in the bottom-right corner of your screen. Right-click directly on the time display, and a menu appears with several options. Look for "Adjust date/time" or "Date and time settings"—this varies slightly between Windows 10 and Windows 11. Clicking this option opens the Date & Time settings panel where you can view and modify your device's time information. Windows displays your current date, time, and time zone all in one location, making adjustments organized and easy to understand.

Like mobile devices, Windows computers have an automatic time setting. You'll see a toggle labeled "Set time automatically" which should remain enabled under normal circumstances. When this is on, Windows connects to time servers maintained by Microsoft and the National Institute of Standards and Technology (NIST) to keep your clock accurate. Below this, you'll see "Set time zone automatically," which uses your location services and internet connection to determine whether you're observing daylight saving time. For most users in most situations, leaving both of these toggles on prevents time-related problems entirely.

If you need to manually adjust your time zone (for example, if you're in a location Windows doesn't automatically recognize), click on the "Time zone" dropdown menu. This shows a complete list of time zones organized by region and major cities. Select your location from the list. If your computer's time is significantly off and automatic synchronization isn't fixing it, you can manually set it by clicking "Change" under the date and time section. A dialog box appears where you can enter the correct month, day, year, and time using simple number fields. After making changes, click "OK" to apply your adjustments.

Practical Takeaway: If your Windows computer's clock keeps drifting (showing an incorrect time even with automatic updates on), your computer's CMOS battery—the internal battery that maintains time when powered off—may be failing. This requires professional service, but you can continue using automatic time synchronization when connected to the internet.

Setting Time on Mac Computers

Mac computers store time settings in System Preferences, called System Settings in newer versions. Click the Apple menu in the top-left corner and select "System Preferences" or "System Settings." Look for an icon labeled "Date & Time" and click it to open the time settings panel. This panel displays your current date, time, time zone, and whether automatic time updating is active. The interface is clean and straightforward, with fewer options than many other operating systems, reflecting Apple's focus on simplicity. All the controls you need are visible on a single screen.

At the top of the Date & Time window, you'll see a lock icon. If it appears locked (showing a closed padlock), you need administrator permission to make changes. Click the lock and enter your Mac's password to unlock the settings. Once unlocked, you can modify any time-related option. Check the box next to "Set date and time automatically" to have your Mac sync with Apple's internet time servers. This is the recommended setting for the vast majority of users. When this option is enabled, you'll see "Using network time server" displayed below it,
