The name of the currency for the main country using this locale (e.g. 'US Dollar' for the locale en-US). The name will be null if the main country cannot be determined.

Periods of the day (e.g. [AM, PM] for en-US).

Eras for the Gregorian calendar (e.g. AD/BC).

Rules used to determine which day period to use (See dayPeriods below). The rules can either be an array or a single value. If it's an array, consider it as "from" and "to". If it's a single value then it means that the period is only valid at this exact value. There is always the same number of rules as the number of day periods, which means that the first rule is applied to the first day period and so on. You should fallback to AM/PM when there are no rules available.

Day Periods indicate roughly how the day is broken up in different languages (e.g. morning, noon, afternoon, midnight, ...). You should use the function getLocaleExtraDayPeriodRulesto determine which period to use. You should fallback to AM/PM when there are no day periods available.

Time format that depends on the locale.

Range of days in the week that represent the week-end for this locale, based on english days (Sunday = 0, Monday = 1, ...). For example in english the value would be [6,0] for Saturday to Sunday.

Register global data to be used internally by Angular. See the "I18n guide" to know how to import additional locale data.

Some languages use two different forms of strings (standalone and format) depending on the context. Typically the standalone version is the nominative form of the word, and the format version is in the genitive. See the CLDR website for more information.

Multiple widths are available for formats: short (minimal amount of data), medium (small amount of data), long (complete amount of data), full (complete amount of data and extra information).

A key value pair. Usually used to represent the key value pairs from a Map or Object.

A serializable version of the event from onPopState or onHashChange

The different format styles that can be used to represent numbers. Used by the function getLocaleNumberFormat.

Number symbol that can be used to replace placeholders in number patterns. The placeholders are based on english values:

Multiple widths are available for translations: narrow (1 character), abbreviated (3 characters), wide (full length), and short (2 characters, only for days).
