The date.toLocaleString()method is used to convert a date and time to a string using the locale settings.


dateObj.toLocaleString(locales, options)

Parameters: This method accepts two parameters as mentioned above and described below:

  • locales: This parameter is an array of locale strings that contain one or more language or locale tags. Note that it is an optional parameter. If you want to use a specific format of the language in your application then specify that language in the locales argument.
  • Options: It is also an optional parameter and contains properties that specify comparison options. Some properties are localeMatcher, timeZone, weekday, year, month, day, hour, minute, second, etc.

Return values: It returns date and time as a string value in the specific format that is specified by the locale.

Note: The dateObjshould be a valid Date object.

Example 1: Below is the example of the Date toLocaleString()method.


let d = new Date(Date.UTC(2020, 9, 26, 7, 0, 0));
let result = d.toLocaleString();
console.log("Date and Time of apocalypse: "+ result);



Date and Time of apocalypse: 26/10/2020, 12:30:00

Example 2:This code prints the current date and time. Also, In this code toLocaleString()method does not use any parameter so it uses the operating system’s locale’s conventions and returns a result that is machine-specific.


let d = new Date();
let result = d.toLocaleString();
console.log("date and time as a string = " + result);



date and time as a string = 1/9/2023, 1:17:10 PM

Example 3:This code prints the date and time in string format specified by the locale parameter.


let date = new Date(Date.UTC(2018, 5, 26, 7, 0, 0));
let options = { hour12: false };
console.log(date.toLocaleString("en-US", options));



6/26/2018, 12:30:00 PM
6/26/2018, 12:30:00

Note: The toLocaleString()method is different from toLocaleDateString()as toLocaleDateString()converts only the date of a Date object into a string but toLocaleString()converts date and time to a string.
