Likewise, if the toggle is on, then the 24-hour format is active. if you want to use the 24-hour format, make sure the toggle button is on, if it was off before. Your device should immediately update to display the time in the 24-hour format.
What’s the Difference Between 12-Hour and 24-Hour Formats?
12-Hour Format: The time is divided into two periods: AM (from midnight to noon) and PM (from noon to midnight). For example, 3:00 PM means it’s 3 o’clock in the afternoon.
24-Hour Format: Also known as military time, the time runs from 00:00 (midnight) to 23:59 (one minute before the next midnight). For example, 15:00 would indicate 3:00 PM in the 12-hour format.
Additional Tips
Lock Screen Clock Format: Changing the clock format in the settings will also affect how time is displayed on your lock screen. If you use a third-party launcher or clock widget, ensure the widget settings also reflect your desired format.
Time Zone Settings: If you travel between time zones frequently, consider enabling the option to set the time zone automatically. This will help your device adjust the clock format based on your location.
