Change language of Datepicker of Material Angular 4

import {MAT_DATE_LOCALE} from '@angular/material';

&

providers: [{ provide: MAT_DATE_LOCALE, useValue: 'es-ES' }]

Do this in tpv.modules.ts

md-datepicker provides setLocale method which can be used to set any language (list of locale).

Here's an example of setting locale to 'fr':

export class DatepickerOverviewExample {  constructor(private dateAdapter: DateAdapter<Date>) {    this.dateAdapter.setLocale('fr');     }}

One thing to keep in mind, md-datepicker's default date parsing format is mm/dd/yyyy, so if a locale has a different date format (for 'fr' its dd/mm/yyyy), we will need to define a class that extends NativeDateAdapter to parse the new date format. Without setting the proper date format, there will be an issue like this question.

import { NativeDateAdapter, DateAdapter, MD_DATE_FORMATS } from "@angular/material";export class FrenchDateAdapter extends NativeDateAdapter {  parse(value: any): Date | null {    if ((typeof value === 'string') && (value.indexOf('/') > -1)) {      const str = value.split('/');      if (str.length < 2 || isNaN(+str[0]) || isNaN(+str[1]) || isNaN(+str[2])) {        return null;      }      return new Date(Number(str[2]), Number(str[1]) - 1, Number(str[0]), 12);    }    const timestamp = typeof value === 'number' ? value : Date.parse(value);    return isNaN(timestamp) ? null : new Date(timestamp);  }}@Component({  ...  providers: [{provide: DateAdapter, useClass: FrenchDateAdapter}],})

Sorry this should be a comment but I don't have the minimum reputation required.

Here is a good blog post on DatePicker including using it with moment.js as @Gregor Doroschenko mentioned in the above comment.
