A locale is one of the standard codes in the format aa_BB_CC, where aa represents the language and _BB or _BB_CC represents a country variant suffix. For example, it_IT is the locale for Italian as spoken in Italy, de_DE is German as spoken in Germany, and de_CH is Swiss German. Every user session has a locale setting that can affect the language presented by Pega 7 Platform user interface when displaying or entering dates, times, and money amounts.
