The Clock app on your iPhone has some helpful utilities such as setting alarms, timers, or running a stopwatch. You can even customize those features even further, such as setting your alarm so that it only vibrates. But there are some clock-related settings that you might need to adjust, such as whether or the clock on the device is in the 12 or 24 hour format, that you won’t be able to adjust in the Clock app.
Fortunately these settings can be modified through the Settings app instead. So if you find that your iPhone is currently in the 24-hour time format, and that you would prefer to have it in the 12-hour format, then you are able to make that change. Our tutorial below will show you the steps to take in order to achieve this result.
How to Change from 24 Hour to 12 Hour Clock on an iPhone SE
The steps in this article were performed on an iPhone SE in iOS 10.3.2. This assumes that your iPhone is currently in the 24 hour time format, which means that it will go to 13:00 at 1 PM. Switching to the 12 hour time format will revert to the AM and PM 12 hour format.
Step 1: Touch the Settings icon.
Step 2: Choose the General option.
Step 3: Scroll down and select the Date & Time option.
Step 4: Tap the button to the right of 24-Hour Time to turn it off. You will see the AM or PM designation show up immediately to the right of the time at the top of your screen.
Note that you can also control some other time-related options on this screen as well, including whether or not your iPhone time will update automatically for Daylight Savings Time and time zone changes.
