How to Enable or Disable Military Time on iPhone: A Step-by-Step Guide

Switching between standard time and military time on your iPhone is simple. Just access your Settings, tap on General, then Date & Time, and toggle the 24-Hour Time switch. Voila! You’ve either enabled or disabled military time, according to your preference.

After completing this action, your iPhone will display the time in either the 12-hour format (AM/PM) or the 24-hour format, commonly known as military time. This change will be reflected across your device, including the lock screen, home screen, and in apps where the time is displayed.


Ever needed to switch between a 12-hour and a 24-hour clock on your iPhone but weren’t sure how? Whether you’re a military buff, an international traveler, or someone who simply prefers the clarity of a 24-hour format, this article is for you.

The 24-hour clock, often referred to as military time, is a timekeeping convention where the time of day is divided into 24 hours, from midnight to midnight. It’s widely used across the world and especially in professions where precision and clarity about time are crucial – think healthcare, aviation, or the army, of course.

Knowing how to toggle between these time formats on your iPhone can be handier than you think. Maybe you’ve downloaded an app that uses military time, or perhaps you’re syncing your phone with a schedule set in a 24-hour format. Whatever the reason, it’s a simple tweak that can make your life a little bit easier or just fit your personal preference.

Additional Information

Switching to military time on your iPhone is a small change, but like any change, it can take a bit of getting used to. If you’re new to the 24-hour clock format, practice reading the time throughout the day until it becomes second nature. Also, consider how this change might affect other devices you use. For instance, if you wear an Apple Watch, you’ll want to adjust its settings to match your iPhone.

Moreover, think about the apps you regularly use. Certain productivity or scheduling apps might function better with military time settings. Plus, if you travel often or work with international teams, using a 24-hour clock can help you easily adapt to different time zones without the confusion of AM and PM.

Remember, while this setting is easily accessible, it’s an individual preference. Use whichever format makes you comfortable and best suits your lifestyle.
