Intl.Locale.prototype.getHourCycles()
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The getHourCycles() method of Intl.Locale instances returns a list of one or more unique hour cycle identifiers for this locale.
Note:
In some versions of some browsers, this method was implemented as an accessor property called hourCycles. However, because it returns a new array on each access, it is now implemented as a method to prevent the situation of locale.hourCycles === locale.hourCycles returning false. Check the browser compatibility table for details.
Syntax
getHourCycles()
Parameters
None.
Return value
An array of strings representing 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
h12-
Hour system using 1–12; corresponds to 'h' in patterns. The 12 hour clock, with midnight starting at 12:00 am. As used, for example, in the United States.
h23-
Hour system using 0–23; corresponds to 'H' in patterns. The 24 hour clock, with midnight starting at 0:00.
h11-
Hour system using 0–11; corresponds to 'K' in patterns. The 12 hour clock, with midnight starting at 0:00 am. Mostly used in Japan.
h24-
Hour system using 1–24; corresponds to 'k' in pattern. The 24 hour clock, with midnight starting at 24:00. Not used anywhere.
Examples
Obtaining supported hour cycles
If the Locale object doesn't have a hourCycle already, getHourCycles() lists all commonly-used hour cycle identifiers for the given Locale. For examples of explicitly setting a hourCycle, see hourCycle examples.
const arEG = new Intl.Locale("ar-EG");
console.log(arEG.getHourCycles()); // ["h12"]
const jaJP = new Intl.Locale("ja-JP");
console.log(jaJP.getHourCycles()); // ["h23"]
