How to set locale in DatePipe in Angular 2?


I want to display Date using European format dd/MM/yyyy but using DatePipe shortDate format it only display using US date style MM/dd/yyyy.
I'm assuming thats the default locale is en_US. Maybe I am missing in the docs but how can I change the default locale settings in an Angular2 app? Or maybe is there some way to pass a custom format to DatePipe ?

The Best Answer is


As of Angular2 RC6, you can set default locale in your app module, by adding a provider:

  providers: [
    { provide: LOCALE_ID, useValue: "en-US" }, //replace "en-US" with your locale

The Currency/Date/Number pipes should pick up the locale. LOCALE_ID is an OpaqueToken, to be imported from angular/core.

import { LOCALE_ID } from '@angular/core';

For a more advanced use case, you may want to pick up locale from a service. Locale will be resolved (once) when component using date pipe is created:

  provide: LOCALE_ID,
  deps: [SettingsService],      //some service handling global settings
  useFactory: (settingsService) => settingsService.getLanguage()  //returns locale string

Hope it works for you.

Solution with LOCALE_ID is great if you want to set the language for your app once. But it doesn’t work, if you want to change the language during runtime. For this case you can implement custom date pipe.

import { DatePipe } from '@angular/common';
import { Pipe, PipeTransform } from '@angular/core';
import { TranslateService } from '@ngx-translate/core';

  name: 'localizedDate',
  pure: false
export class LocalizedDatePipe implements PipeTransform {

  constructor(private translateService: TranslateService) {

  transform(value: any, pattern: string = 'mediumDate'): any {
    const datePipe: DatePipe = new DatePipe(this.translateService.currentLang);
    return datePipe.transform(value, pattern);


Now if you change the app display language using TranslateService (see ngx-translate)


the formats within your app should automatically being updated.

Example of use:

<p>{{ 'note.created-at' | translate:{date: note.createdAt | localizedDate} }}</p>
<p>{{ 'note.updated-at' | translate:{date: note.updatedAt | localizedDate:'fullDate'} }}</p>

or check my simple "Notes" project here.
