Intl.Locale.prototype.hourCycles

The hourCycles accessor property of Intl.Locale instances returns a list of one or more unique hour cycle identifiers for this 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 returns an array of all hour cycle types commonly used for the Locale, sorted in descending preference. If the Locale already has an hourCycle, then the returned array contains that single value.

Below is a list of supported hour cycle types.

Supported hour cycle types

h11 Hour system using 0–11; corresponds to 'K' in patterns. The 12 hour clock, with midnight starting at 0:00 am.
h24 Hour system using 1–24; corresponds to 'k' in pattern. The 24 hour clock, with midnight starting at 24:00.

Examples

Obtaining supported hour cycles

If the Locale object doesn't have a hourCycle already, the hourCycles property lists all commonly-used collation types for the given Locale. For examples of explicitly setting a hourCycle, see hourCycle examples.

const arEG = new Intl.Locale("ar-EG");
console.log(arEG.hourCycles); // ["h12"]

const jaJP = new Intl.Locale("ja-JP");
console.log(jaJP.hourCycles); // ["h23"]
