Many iPhone users want to switch their device's time display from the standard 12-hour format to the 24-hour military time format. This can be confusing if you are unfamiliar with the iPhone settings or if the option seems hidden. Changing to military time helps avoid AM/PM confusion and is preferred in professional or international contexts.
This guide explains how to change the time format on your iPhone to military time quickly and easily. You will learn the exact steps, prerequisites, troubleshooting tips, and best practices to ensure your iPhone shows time in 24-hour format consistently.
How do you change time to military time on iPhone?
You can change your iPhone’s time to military time by enabling the 24-hour time format in the Settings app under Date & Time options.
To do this, open Settings, tap General, then Date & Time, and toggle on the 24-Hour Time switch. This immediately switches your clock to military time across the system.
Using military time removes AM/PM indicators and displays hours from 00 to 23, which is useful for clarity and international standards.
What prerequisites are required for changing iPhone time to military time?
- Updated iOS version: Ensure your iPhone runs iOS 12 or later for consistent access to 24-hour time settings and improved stability.
- Unlocked device access: You need to access the Settings app, so your device must be unlocked and not restricted by parental controls.
- Basic navigation skills: Familiarity with the iPhone Settings app helps you find the correct menu quickly.
- Correct time zone set: Your iPhone should have the correct time zone configured to display accurate time after switching formats.
Why does my iPhone not show the 24-hour time option?
Sometimes the 24-hour time toggle may be missing or greyed out due to region settings or restrictions. The 24-hour time option depends on your iPhone’s region format, which influences how dates and times are displayed.
If your region is set to a country that primarily uses 12-hour time, the option might be disabled. Changing the region to one that uses 24-hour time, like the United Kingdom or Germany, can enable the toggle.
Additionally, if Screen Time restrictions or device management profiles are active, they might prevent changing time formats. Check these settings to ensure no restrictions block the option.

Can I change military time format back to 12-hour on iPhone?
Yes, you can revert your iPhone’s time display back to the 12-hour format by disabling the 24-Hour Time toggle in the Date & Time settings. This switches the clock back to showing AM and PM indicators.
Simply go to Settings > General > Date & Time and toggle off the 24-Hour Time option. The change applies system-wide immediately.
What are the differences between 12-hour and 24-hour time formats on iPhone?
The 12-hour format divides the day into two periods: AM (midnight to noon) and PM (noon to midnight), displaying hours from 1 to 12. The 24-hour format counts hours from 00 to 23 without AM/PM.
Military time is the 24-hour format, preferred for clarity and avoiding confusion in schedules, especially in international or technical environments.
How does changing to military time affect alarms and calendar events?
Changing to military time updates how alarms and calendar events display time but does not affect their functionality. Alarms set for 7 AM will show as 07:00, and 7 PM will show as 19:00, making it easier to distinguish times.
This change is purely visual and helps prevent misinterpretation of scheduled times.
What if my iPhone time is incorrect after switching to military time?
If your iPhone shows the wrong time after switching formats, verify your time zone settings and ensure "Set Automatically" is enabled. Incorrect time zones can cause mismatches regardless of format.
Restarting the device can also help refresh the system clock and correct display issues.
Are there apps that override the iPhone’s military time setting?
Some third-party apps may use their own time format settings independent of the iPhone system. Check app-specific settings to ensure they display time in your preferred format.
Most native apps respect the system-wide 24-hour time setting.
Can I use Siri to change my iPhone to military time?
Currently, Siri does not support changing the time format directly via voice commands. You must manually change the setting through the Settings app.
Siri can, however, tell you the current time in 24-hour format if your device is set accordingly.
Conclusion
Changing your iPhone to military time is a straightforward process that improves clarity by removing AM/PM confusion. By enabling the 24-Hour Time toggle in the Date & Time settings, you switch your device to a 24-hour format used worldwide in professional and technical contexts.
Developers and users working across time zones or in international environments benefit from this format. Remember to check region settings and restrictions if you encounter issues. Following best practices ensures consistent and accurate time display across your iPhone and apps.
