The 12-hour format which ends with either AM or PM is quite popular in the US. However, for the rest of the world, the 24-hour format is mostly preferred especially as it seems much easier to measure time beyond noon. As Windows 10 is an operating system made by a US company, its time setting is set to 12-hour by default.
To fix that, we can manually switch from 12-hour to 24-hour in an instant, without recalibrating the internal clock again, thanks to the internet-based clock synchronization.
Follow these steps to enable 24-hour format on Windows 10.
1. Click the clock on the right side of Taskbar, and hit Date and time settings.
