Free Guide to Changing Your Phone's Time and Date Settings

Understanding Your Phone's Time and Date System

Every smartphone contains an internal clock that runs continuously, even when you're not using it. This clock powers the timestamp on your text messages, the wake-up times on your alarms, and the scheduling features in your calendar. Your phone's operating system—whether it's Android, iOS, or another platform—relies on accurate time and date information to function properly across all its features and apps.

The time and date settings on your phone work together with your device's hardware and software. When you set a time zone, your phone automatically adjusts the display to show the correct local time. When you set the date, your phone uses this information to organize files, schedule reminders, and manage time-sensitive functions. Understanding how these systems work together helps you know why changing these settings matters and how to do it correctly.

Your phone typically has two ways to keep time. First, it can sync with your mobile network provider's time servers, which receive their time from atomic clocks maintained by governments and scientific institutions. Second, your phone can use GPS signals (if you have location services enabled) to receive precise time data. Many phones also offer a manual option where you set the time yourself, though this is less common because automatic synchronization is more convenient and accurate.

Different regions around the world observe different time zones. When you travel or move to a new location, updating your phone's time zone ensures that your alarms go off at the right time and that your scheduled appointments reflect the local time correctly. The date system on your phone follows a calendar format—typically showing the month, day, and year—which may vary depending on your region and your phone's settings.

Practical takeaway: Your phone's time and date settings are interconnected systems that affect everything from your alarms to your calendar reminders. Knowing how these systems work gives you confidence when you need to make changes to these settings.

How to Change Time and Date Settings on Android Devices

Android phones offer straightforward methods to adjust time and date settings. Most Android devices follow a similar process, though the exact menu names may vary slightly depending on the manufacturer and the version of Android your phone runs. The settings application is your main hub for making these changes, and you can access it from your home screen or by swiping down from the top of your screen to view quick settings.

To begin changing your time and date on Android, open the Settings application. Look for a section labeled "System," "General," or "About phone," depending on your device's manufacturer. Within that section, you'll find an option for "Date and time" or similar wording. Once you tap this option, you'll see several choices. Most Android phones have an option called "Automatic date and time" or "Use network-provided time," which is typically turned on by default. When this setting is enabled, your phone receives time information from your mobile network provider and updates itself without any action from you.

If you need to set the time manually, first turn off the automatic setting. You'll then see separate fields where you can input the hour and minute. Android devices typically use a 12-hour format (with AM/PM options) or a 24-hour format, depending on your region and your personal preferences. After setting the time, look for a field to set the date. This field usually shows the month, day, and year. Tap on each component to change it to the correct value.

Time zone selection is another important setting within the date and time menu. Most Android phones have an "Automatic time zone" option that uses your location to determine the correct zone. If you disable this, you can manually select your time zone from a list of all zones worldwide. The list is typically organized by continent or region, making it easier to find your location. Some phones also display the UTC (Coordinated Universal Time) offset, which shows how many hours ahead or behind the UTC standard your time zone is.

After making your changes, return to your home screen to confirm the new time and date appear correctly in your status bar. You can also verify the settings took hold by opening your Settings application again and navigating back to the date and time section. If you accidentally changed a setting incorrectly, simply return to this menu and adjust it again—there's no risk to making corrections.

Practical takeaway: Android devices consolidate time and date controls in a single settings menu, and automatic synchronization handles updates for you once enabled. Manual changes are reversible, so you can adjust settings without concern.

How to Change Time and Date Settings on iOS Devices

Apple's iOS devices—including iPhones and iPads—store their time and date settings in a slightly different location than Android phones, but the process is equally straightforward. Unlike Android, iOS doesn't organize all settings under a single "System" section, so you'll need to know where to look. The Settings application on iOS is organized by feature categories rather than by broad system sections.

To access time and date settings on an iOS device, open the Settings app from your home screen. Scroll down until you find "General," and tap it. Within the General menu, look for "Date & Time." This section contains all the controls you need to manage your device's clock and calendar. Like Android devices, iOS phones have an automatic setting that keeps your time synchronized with your mobile network. This setting is called "Set Automatically" and is typically enabled by default.

When "Set Automatically" is turned on, your iPhone or iPad receives time information from your wireless carrier and, if location services are enabled, from GPS satellites. Your device also uses this automatic setting to determine your time zone based on your location. If you're traveling to a different time zone and prefer to manually select your zone rather than relying on automatic detection, you can disable "Set Automatically" and then tap on the time zone option to choose your location from a list.

If you need to manually set the time on an iOS device, you'll notice that the time field only appears after you disable the "Set Automatically" option. Once you do this, you can tap the time field and adjust the hours and minutes using a dial-like interface or by typing directly. The interface adapts based on whether you've set your device to display time in 12-hour or 24-hour format—a setting you can change within the same Date & Time menu.

iOS devices also allow you to set a custom date if needed, though this option appears only when automatic setting is turned off. Simply tap the date field and adjust the month, day, and year. After making any changes, exit the Settings app and check your status bar to confirm the new time and date display correctly. You can reopen Settings anytime to verify your adjustments or make additional changes.

Practical takeaway: iOS consolidates date and time settings in a single location within the General menu, with automatic synchronization as the default. Disabling automatic setting reveals manual options for time, date, and time zone selection.

Time Zones and Daylight Saving Time Explained

Earth is divided into 24 major time zones, each representing one hour of difference from the next. These zones were established in the late 1800s to create a standard system for timekeeping across different regions. Your phone's time zone setting tells it which of these zones you're currently in, so it can display the correct local time. Most time zones are centered on meridian lines (invisible lines running from north to south) that are exactly 15 degrees of longitude apart, since Earth rotates 15 degrees per hour.

Daylight Saving Time (DST) is a practice observed in many regions where clocks are moved forward by one hour in spring and backward by one hour in fall. The stated purpose of this change is to make better use of daylight during evening hours. However, not all regions observe DST. Some areas, particularly near the equator or in certain countries, keep the same time year-round. In the United States, most states observe DST, but Hawaii, most of Arizona, and several U.S. territories do not. This means the time difference between locations can change depending on the time of year.

Most modern phones handle DST changes automatically when you have automatic date and time settings enabled. Your phone's operating system contains a database of DST rules for different regions around the world. When the date changes to a DST transition day, your phone's time automatically adjusts. This is why keeping automatic settings enabled is convenient—you don't need to remember to manually change your time when DST begins or ends. If you travel to a region that doesn't observe DST, or if you travel between regions with different DST practices, automatic time zone detection helps your phone make the correct adjustment.
