Globalization in Angular Calendar component

5 Apr 20258 minutes to read

Globalization is the combination of internalization and localization. You can adapt the component to various languages by parsing and formatting the date or number Internationalization and also add culture specific customization and translation to the text localization.

By default, Calendar date format, week and month names are specific to American English culture. It utilizes the Essential® JavaScript 2 Internationalization package to parse and format the date object based on the culture by uses the official UNICODE CLDR JSON data and also it provides the loadCldr method to load the culture specific CLDR JSON data.

To go with the different culture other than English, follow the below steps.

  • Install the CLDR-Data package by using the below command (it installs the CLDR JSON data). To know more about CLDR-Data refer the CLDR-Data link.

    npm install cldr-data --save

Once the package installed, you can find the culture specific JSON data under the location /node_modules/cldr-data.

  • Now import the installed CLDR JSON data into the app.component.ts file.

  • Now use the loadCldr method to load the culture specific CLDR JSON data from the installed location to app.component.ts file.

  • Calendar displayed Sunday as the first day of week based on default culture (“en-US”). If you want to display the Calendar with loaded culture’s first day of week, you need to import weekdata.json file from the cldr-data/suppemental as given in the code example.

    //import the loadCldr from ej2-base
import { loadCldr} from '@syncfusion/ej2-base';

declare var require: any;

loadCldr(
    require('cldr-data/supplemental/numberingSystems.json'),
    require('cldr-data/main/de/ca-gregorian.json'),
    require('cldr-data/main/de/numbers.json'),
    require('cldr-data/main/de/timeZoneNames.json'),
    require('cldr-data/supplemental/weekdata.json')); // To load the culture based first day of week

The Localization library allows you to localize default text content of the Calendar. The Calendar component has static text for today feature that can be changed to other cultures (Arabic, Deutsch, French, etc.) by defining the locale value and translation object.

Locale keywords Text
today Name of the button to choose Today date.

  • Before changing to a culture other than English, ensure that locale text for the concerned culture is loaded through load method of L10n class.

    //Load the L10n, loadCldr from ej2-base
import { loadCldr, L10n } from "@syncfusion/ej2-base";

//load the locale object to set the localized placeholder value
L10n.load({
  de: {
    calendar: {
              today:"heute"
}
  }
});

  • Set the culture by using the locale property. The below code example, initialize the Calendar component in German culture.

    import { Component } from '@angular/core';
//import the loadCldr from ej2-base
import { loadCldr, L10n } from '@syncfusion/ej2-base';

declare var require: any;

loadCldr(
    require('cldr-data/supplemental/numberingSystems.json'),
    require('cldr-data/main/de/ca-gregorian.json'),
    require('cldr-data/main/de/numbers.json'),
    require('cldr-data/main/de/timeZoneNames.json')
    );
@Component({
    selector: 'app-root',
    template: `
    <!-- Sets the value, locale -->
    <ejs-calendar [value]='dateValue' locale='de'></ejs-calendar>`
})

export class AppComponent {
    public dateValue: Object = new Date();
    ngOnInit(): void {
    /*loads the localization text*/
    L10n.load({
      'de': {
        'calendar': {
          today:"heute"
        }
      }
    });
  }
    constructor() {
    }
}

The following example demonstrates the Calendar in German culture.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { CalendarModule } from '@syncfusion/ej2-angular-calendars'




import { Component } from '@angular/core';
import { loadCldr, L10n } from '@syncfusion/ej2-base';
// Here we have referred local json files for preview purpose
import * as numberingSystems from './numberingSystems.json';
import * as gregorian from './ca-gregorian.json';
import * as numbers from './numbers.json';
import * as timeZoneNames from './timeZoneNames.json';

loadCldr(numberingSystems, gregorian, numbers, timeZoneNames);

@Component({
imports: [
        
        CalendarModule //declaration of ej2-angular-calendars module into NgModule
    ],


standalone: true,
    selector: 'app-root',
    template: `
    <!-- Sets the value, locale -->
    <ejs-calendar [value]='dateValue' locale='de'></ejs-calendar>`
})

export class AppComponent {
   public dateValue: Object = new Date();
    ngOnInit(): void {
    /*loads the localization text*/
    L10n.load({
      'de': {
        'calendar': {
           today:"heute"
        }
      }
    });
  }
    constructor() {
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Right-To-Left

The Calendar supports right-to-left functionality for languages like Arabic, Hebrew to displays the text in the right-to-left direction. Use enableRtl property to set the RTL direction.

The following example demonstrates the Calendar in Arabic culture with enableRtl property.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { CalendarModule } from '@syncfusion/ej2-angular-calendars'




import { Component } from '@angular/core';
import { loadCldr, L10n} from '@syncfusion/ej2-base';
// Here we have referred local json files for preview purpose
import * as numberingSystems from './numberingSystems.json';
import * as gregorian from './ca-gregorian.json';
import * as numbers from './numbers.json';
import * as timeZoneNames from './timeZoneNames.json';

loadCldr(numberingSystems, gregorian, numbers, timeZoneNames);

@Component({
imports: [
        
        CalendarModule //declaration of ej2-angular-calendars module into NgModule
    ],


standalone: true,
    selector: 'app-root',
    template: `
         <!-- Sets the value, locale,enableRtl -->
        <ejs-calendar [value]='dateValue' locale='ar' enableRtl='true'></ejs-calendar>
        `
})

export class AppComponent {
   public dateValue: Object = new Date();
    ngOnInit(): void {
       L10n.load({
        'ar': {
          'calendar': { today: "اليوم"}
        }
      });
    }
    constructor() {
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
