Converting 'human' date string of different language to date object in JavaScript

rated 0 times [ 86] [ 5] / answers: 1 / hits: 5209 / 4 Years ago, tue, january 28, 2020, 12:00:00

I am trying to convert the following set of strings:

juin 2016 septembre 2013 janvier 2013 juillet 2010

All of which are in French, so when I use new Date() it defaults to January:

new Date('juin 2016') // -> Fri Jan 01 2016 00:00:00

new Date('août 2013') // -> Tue Jan 01 2013 00:00:00

Whereas it should be:

new Date('juin 2016') // -> Wed Jun 01 2016 00:00:00

new Date('août  2013') // -> Thu Aug 01 2013 00:00:00

Is there a way for the months from other languages be recognized?
Or the only way is to manually translate the months into english?

Unfortunately there is no native API for this.

If you know the format, it is easy to convert, without a massive library:

const months = [janvier, février, mars, avril, mai, juin, juillet, août, septembre, octobre, novembre, décembre];



function getDateFromMonthYear(input) {

  const parts = input.split( );

  if (parts.length != 2) throw Error(`Expected 2 parts, got ${parts.length}: ${input}`);

  const [searchMonth, year] = parts;

  const month = months.indexOf(searchMonth.toLowerCase());

  if (month < 0) throw Error(`Unknown month: ${searchMonth}`);

  return new Date(year, month, 1);

}





[juin 2016, septembre 2013, janvier 2013, juillet 2010].forEach(date =>

  console.log(

    date,

     -> ,

    getDateFromMonthYear(date).toDateString()

  )

);

There is a new Intl API that you can use to get the month-names of supported languages:

function getFullMonthName(locale) {

  const int = new Intl.DateTimeFormat(locale, { month: long });

  const out = [];

  for (let month = 0; month < 12; ++month) out[month] = int.format(new Date(2020, month, 3));

  return out;

}



[sv-SE, fr-FR, en-US, en-UK].forEach(locale => console.log(locale, getFullMonthName(locale).join(', ')));
