Regional settings and formats
Regional settings influence how items like your date/time, numeric, and currency data types appear when you apply formatting options. For example, a user in the United States might use forward slashes as a separator and the format month-day-year to enter a date value for a date/time field (for example, 8/29/2019); however, a user in Korea might see the same date using hyphens as a separator and using the format year-month-day (for example, 2019-08-29).
This principle also applies to numerical and financial data. Users in the United Kingdom use the English pound symbol (£) to represent local currency in financial data, while users in Germany use the Euro symbol (€).
Some regional settings, such as numerical, date, time, and calendar format, can be set via a user’s operating system but you might need to implement other regional conventions in your application. These conventions include postal address formats, telephone number formats, and units of measurement.
The collection of these settings is typically defined by a user’s locale, which is usually specified by parameters such as language, country/region, and script.
