To change the default date, time, number, and currency format, select the Formats tab of the Region and Language application. You will be presented with a short list of available formats.

By default, this list only contains a few of the available formats. To add another format, click the + (the plus sign) button below the list. A dialog window appears, allowing you to select the desired format according to a region. The input field at the bottom part of the dialog window allows you to reduce the number of displayed items by typing first few letters of the region name in it (for example, “slov” for Slovakia). Once you select a region, click the Select button to confirm your choice.

To choose a particular format from the list, click its name to select it. The changes will take effect the next time you log in to the system.
