A guide on obtaining the date format according to locale using Intl.DateTimeFormat within JavaScript

Can someone assist me in obtaining the standard date format (such as MM/DD/YYYY) based on a specified local id? The code snippet provided below is not returning the desired format. Any guidance on how to achieve this would be greatly appreciated.

var dateFormat = new Intl.DateTimeFormat("as-IN").

Answer №1

My approach involved initially creating a dummy date in accordance with the locale. Subsequently, I proceeded to substitute specific date components (day, month, year) with the standard placeholders DD, MM, YYYY.

Below is the code snippet:

/**
 * Returns date format utilized by Intl.DateTimeFormat (for specified `options`).
 * Example for Serbia: `DD/MM/YYYY`
 *
 * **Note** that this will consistently output the two-digit format for day and month along with four digits for year (e.g. `DD/MM/YYYY`)
 */
export function getIntlDateFormatForLocale(locale: string, options?: Intl.DateTimeFormatOptions) {
  const year = 2222
  const month = 12
  const day = 15
  const date = new Date(year, month - 1, day)
  const formattedDate = new Intl.DateTimeFormat(locale, options).format(date)
  return formattedDate.replace(`${year}`, 'YYYY').replace(`${month}`, 'MM').replace(`${day}`, 'DD')
}

Important to mention: The resulting format from this function presents date parts in their two-digit form. Therefore, if a user's locale displays single-digit dates, using this format will result in double-digit representations.

For instance: If a user's locale generates dates like 1/1/2021, it will be transformed into 01/01/2021 when applying the format obtained from this function.

This method may not yield accurate results when the format contains weekdays (e.g. Mon), Mandarin/Japanese/Arabic numerals, etc.

While there might be certain limitations, this solution sufficed for my particular requirements ;)

Answer №2

Presented here is a simple function that retrieves the date format based on the user's locale:

        let dateFormat ='';
        for(let i=0;i<new Intl.DateTimeFormat(navigator.language).formatToParts().length;i++){
            if(new Intl.DateTimeFormat(navigator.language).formatToParts()[i].type === "year") {
                dateFormat += "yyyy";
            } else if(new Intl.DateTimeFormat(navigator.language).formatToParts()[i].type === "literal"){
                dateFormat += new Intl.DateTimeFormat(navigator.language).formatToParts()[i].value;
            } else if(new Intl.DateTimeFormat(navigator.language).formatToParts()[i].type === "day") {
                dateFormat += "dd";
            } else if(new Intl.DateTimeFormat(navigator.language).formatToParts()[i].type === "month") {
                dateFormat += "MM";
            }
        }
        console.log(dateFormat);
