Internationalization is the process of changing the format of dates and numbers to the one used in your region and translating user-interface text to your language. For example, the 12th of January 1990 will look like 01/12/90 in the American date format and 12.01.1990 in the German one. The date format in TrackStudio is used when displaying and inputting information. 

Note: all input fields which require the date to be entered are marked with the icon, pressing it will open a popup calendar where you can select the date. This calendar already takes into account the appropriate date format. 

Similarly, some user-interface text like Your Name in English can be translated to Ihr Name for German locales. 

User locale is specified separately for each user in the user settings (User Management->User->Edit). There is a drop-down box with the list of available locales on this page. The list is determined by the settings of Java Virtual Machine on which TrackStudio is running.This list likely contains the locale that you need, but there may be no resources in TrackStudio for some locales. The resources are language files containing the translation of all text messages in TrackStudio into your language and a set of images that determine the appearance of TrackStudio. All the necessary resources for the English and Russian locales are already included in the standard TrackStudio. If you want to localize TrackStudio, consult the section Localizing the Interface. 

If you select a locale for which there are no resources, the date format will change to the selected language, but the interface will remain English (by default).
