We need to be using this format when dealing with dates in JavaScript ISO 8601, of course! This is the name of the international standard for communicating date and time data. And once you spend a little time going over the basics, your confidence will grow. Show an alternative way to use arguments instead of strings to create a date object.ĭates are tricky, but they're also incredibly helpful to use.Turn a wee ol' string into a proper date object using JavaScript.But parsing dates using JavaScript can be a little.well, interesting. toLocaleDateString ( "ja-JP-u-ca-japanese" ) ) // "24/12/20" // when requesting a language that may not be supported, such as // Balinese, include a fallback language, in this case IndonesianĬonsole. toLocaleDateString ( "ar-EG" ) ) // "٢٠/١٢/٢٠١٢" // for Japanese, applications may want to use the Japanese calendar, // where 2012 was the year 24 of the Heisei eraĬonsole. toLocaleDateString ( "fa-IR" ) ) // "۰" // Arabic in most Arabic speaking countries uses real Arabic digitsĬonsole. 20." // Event for Persian, It's hard to manually convert date to Solar HijriĬonsole. ![]() toLocaleDateString ( "en-GB" ) ) // "" // Korean uses year-month-day orderĬonsole. toLocaleDateString ( "en-US" ) ) // "" // British English uses day-month-year orderĬonsole.

Implementations without Intl.DateTimeFormat support are asked to ignore both parameters, making the locale used and the form of the string returned entirely implementation-dependent. In implementations that support the Intl.DateTimeFormat API, these parameters correspond exactly to the Intl.DateTimeFormat() constructor's parameters. The locales and options arguments customize the behavior of the function and let applications specify the language whose formatting conventions should be used.
