A locale is a set of environmental variables that defines the language, country, and character encoding settings (or any other special variant preferences) for your applications and shell session on a Linux system.
Locale affects things such as the time/date format, the first day of the week, numbers, currency and many other values formatted in accordance with the language or region/country.
