Glancing at your iPhone’s clock is a convenient way to track the time, especially if you don’t wear a watch. If you are accustomed to a 24-hour clock, however, it can become a bit annoying to keep looking at the iPhone’s default 12-hour clock display. Like many of the iPhone’s other features and utilities, you can configure the clock display. The option to convert the clock to the 24-hour format is on the device’s Time and Display screen.

Step 1

Select the "Settings" icon on your iPhone's home screen to display the Settings menu.

Step 2

Select "General" from the list of options to open the General screen.

Step 3

Select "Date and Time" to open the Date and Time screen.

Step 4

Tap the "24-Hour Time" ON/OFF switch to the "ON" position. The clock immediately changes to the 24-hour time format.
