Use a 24 Hour Clock on the iPad & iPhone
The iPhone and iPad default to use a 12 hour clock in the USA and Canada, but you can easily switch to 24 hour time (often called Military time) through a quick settings adjustment:
- Open “Settings” and tap on “General”
- Scroll down to “Date & Time” and flip “24-Hour Time” to ON, then close out of Settings
The change takes effect immediately and impacts all iOS system clocks including the time show on the lock screen.
This can be helpful when traveling to other countries that don’t use the 12 hour notation, or if you just prefer to use the 24 hour clock.
