Globalization in Angular Daterangepicker component

27 Apr 202415 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, DateRangePicker date format, week, and month names are specific to the English culture. It utilizes the Essential JavaScript 2 Internationalization package to parse and format the date object based on the culture by using the official UNICODE CLDR JSON data. 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 all the CLDR JSON data). To
    know 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.

  • DateRangePicker displayed Sunday as the first day of week based on default culture (“en-US”). If you want to display the DateRangePicker 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 { 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 DateRangePicker. The DateRangePicker 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
placeholder Hint to describe expected value in input element.
startLabel Label to represent the start date.
endLabel Label to represent the end date.
applyText Text present in the apply button.
cancelText Text present in the cancel button.
selectedDays Text to represent selected days.
days Text represents days.
customRange Text present in the custom range button in presets container.
  • Before changing a culture other than English, ensure that locale text for the concern culture is loaded through L10n.load method.
//Load the L10n from ej2-base
import { L10n } from '@syncfusion/ej2-base';

//load the locale object to set the localized placeholder value
L10n.load({
    'de': {
        'daterangepicker': {  placeholder: 'Wählen Sie einen Bereich aus',
    startLabel: 'Wählen Sie Startdatum',
    endLabel: 'Wählen Sie Enddatum',
    applyText: 'Sich bewerben',
    cancelText: 'Stornieren',
    selectedDays: 'Ausgewählte Tage',
    days: 'Tage',
    customRange: 'benutzerdefinierten Bereich'
     }
    }
});
  • Set the culture by using the locale property. In this below code example, initialize the DateRangePicker component in German culture with corresponding localized text.
import { Component } from '@angular/core';
import { L10n, 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')
);

@Component({
    selector: 'app-root',
    template: `
        <ejs-daterangepicker locale='de'></ejs-daterangepicker>
        `
})

export class AppComponent {
    constructor() {
    }
    ngOnInit(): void {
        L10n.load({
            'de': {
                'daterangepicker': {
                    placeholder: 'Wählen Sie einen Bereich aus',
                    today:"heute"
                    startLabel: 'Wählen Sie Startdatum',
                    endLabel: 'Wählen Sie Enddatum',
                    applyText: 'Sich bewerben',
                    cancelText: 'Stornieren',
                    selectedDays: 'Ausgewählte Tage',
                    days: 'Tage',
                    customRange: 'benutzerdefinierten Bereich'
                }
            }
        });
    }
}

The following sample demonstrate the DateRangePicker component in German culture.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { DateRangePickerModule } 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 detimeZoneNames from './timeZoneNames.json';

loadCldr(numberingSystems, gregorian, numbers, detimeZoneNames);

@Component({
imports: [
        
        DateRangePickerModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<ejs-daterangepicker locale='de'></ejs-daterangepicker>`
})

export class AppComponent {
    constructor() {
    }
    ngOnInit(): void {
        L10n.load({
            'de': {
                'daterangepicker': { placeholder: 'Wählen Sie einen Bereich aus',
                today:"heute",
                startLabel: 'Wählen Sie Startdatum',
                endLabel: 'Wählen Sie Enddatum',
                applyText: 'Sich bewerben',
                cancelText: 'Stornieren',
                selectedDays: 'Ausgewählte Tage',
                days: 'Tage',
                customRange: 'benutzerdefinierten Bereich'
                }
            }
        });
    }
}
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 DateRangePicker supports RTL (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 below code example demonstrates the DateRangePicker component in Hebrew culture, also explains how to set the localized text to the placeholder using L10n.load method.

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

declare var require: any;

loadCldr(
    require('cldr-data/supplemental/numberingSystems.json'),
    require('cldr-data/main/he/ca-gregorian.json'),
    require('cldr-data/main/he/numbers.json'),
    require('cldr-data/main/he/timeZoneNames.json')
);

@Component({
    selector: 'app-root',
    template: `<ejs-daterangepicker locale='he' [enableRtl]='isRTL'></ejs-daterangepicker>`
})

export class AppComponent {
    public isRTL: boolean = true;
    constructor() {
    }
    ngOnInit(): void {
        L10n.load({
            'he': {
                'daterangepicker': { placeholder: 'בחר טווח',
                today:'היום',
        startLabel: 'תווית התחלה',
        endLabel: 'ח',
        applyText: 'להחיל טקסט',
        cancelText: 'בטל טקסט',
        selectedDays: 'ימים נבחרים',
        days: 'أימים',
        customRange: 'טווח מותאם אישית'
         }
         }
    });
    }
}

The following example demonstrates the DateRangePicker in Hebrew culture with right-to-left direction.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { DateRangePickerModule } 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 hetimeZoneNames from './timeZoneNames.json';

loadCldr(numberingSystems, gregorian, numbers, hetimeZoneNames);

@Component({
imports: [
        
        DateRangePickerModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<ejs-daterangepicker locale='he' [enableRtl]='isRTL'></ejs-daterangepicker>`
})

export class AppComponent {
    public isRTL: boolean = true;
    constructor() {
    }
    ngOnInit(): void {
        L10n.load({
            'he': {
                'daterangepicker': { placeholder: 'בחר טווח',
                 today:'היום',
        startLabel: 'תווית התחלה',
        endLabel: 'ח',
        applyText: 'להחיל טקסט',
        cancelText: 'בטל טקסט',
        selectedDays: 'ימים נבחרים',
        days: 'أימים',
        customRange: 'טווח מותאם אישית'
         }
        }
    });
}
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Date format customization

Representation of start and end date strings can be customized to required format by using format property.
By default, it will set based on the culture.
To know more about the date format standards, refer to the Internationalization Date Format section.
In below sample, the date strings are formatted to yyyy-MM-dd and separator between the date ranges is set to “to”.

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




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

@Component({
imports: [
        
        FormsModule,
        DateRangePickerModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<ejs-daterangepicker [format]='dateFormat' separator='to' placeholder='Select a range'></ejs-daterangepicker>`
})
export class AppComponent {
    public dateFormat: String = "yyyy-MM-dd";
    constructor() {
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
