Intl.Locale.prototype.hourCycles

The Intl.Locale.prototype.hourCycles property is an accessor property which returns a list of one or more unique hour cycle identifiers for the Locale.

Description

There are two main types of time keeping conventions (clocks) used around the world: the 12 hour clock and the 24 hour clock. The hourCycles property makes it easier to access all clock types available for a particular locale. Like other additional locale data, the hour cycle type is an extension subtag, which extends the data contained in a locale string. The hour cycle type can have several different values, which are listed in the table below.
