Globalization in EJ2 TypeScript Calendar control
16 Jun 202311 minutes to read
Globalization is the combination of adapting the component to various languages by means of parsing and formatting the date or number Internationalization
and also by adding cultural specific customizations and translating the text localization
By default, the Calendar date format, week, and month names are specific to American English culture. It uses the Essential JavaScript 2 Internationalization
package to parse and format date object based on the culture using the official UNICODE CLDR
JSON data. It provides the loadCldr
method to load the culture-specific CLDR JSON data.
All the Essential JS 2 component are specific to English culture (‘en-US’). If you want to go with the different culture other than English
, follow the below steps.
- Install the
CLDR-Data
package by using the below command (installs the CLDR JSON data). To know more about CLDR data, refer to theCLDR-Data
link.
npm install cldr-data --save
Once the package is installed, the culture-specific JSON data will be available in /node_modules/cldr-data
.
- Now, import the installed CLDR JSON data to the
app.ts
file. To import JSON data, install the JSON plugin loader. In the example, SystemJS JSON plugin loader is used.
npm install systemjs-plugin-json --save-dev
- After it is installed, configure the
system.config.js
settings as given below to map thesystemjs-plugin-json
loader.
System.config({
paths: {
'npm:': './node_modules/',
'syncfusion:': 'npm:@syncfusion/'
},
map: {
app: 'app',
//Syncfusion packages mapping
"@syncfusion/ej2-base": "syncfusion:ej2-base/dist/ej2-base.umd.min.js",
"@syncfusion/ej2-data": "syncfusion:ej2-data/dist/ej2-data.umd.min.js",
"@syncfusion/ej2-inputs": "syncfusion:ej2-inputs/dist/ej2-inputs.umd.min.js",
"@syncfusion/ej2-buttons": "syncfusion:ej2-buttons/dist/ej2-buttons.umd.min.js",
"@syncfusion/ej2-splitbuttons": "syncfusion:ej2-splitbuttons/dist/ej2-splitbuttons.umd.min.js",
"@syncfusion/ej2-lists": "syncfusion:ej2-lists/dist/ej2-lists.umd.min.js",
"@syncfusion/ej2-popups": "syncfusion:ej2-popups/dist/ej2-popups.umd.min.js",
"@syncfusion/ej2-calendars": "syncfusion:ej2-calendars/dist/ej2-calendars.umd.min.js",
"cldr-data": 'npm:cldr-data',
//systemjs-plugin-json loader package mapping
"plugin-json": "npm:systemjs-plugin-json/json.js"
},
meta: {
'*.json': { loader: 'plugin-json' }
},
packages: {
'app': { main: 'app', defaultExtension: 'js' },
'cldr-data': { main: 'index.js', defaultExtension: 'js' }
}
});
System.import('app');
-
Now, use the
loadCldr
method to load the culture-specific CLDR JSON data from the installed location toapp.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 importweekdata.json
file from thecldr-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 thelocale
value and translation object.
Locale keywords | Text |
---|---|
today | Name of the button to choose Today date. |
- Before changing the culture other than
English
, ensure that locale text for the concerned culture is loaded throughload
method of
L10n class.
//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': {
'calendar': { today: 'heute'}
}
});
- Set the culture by using the
locale
property. The code example initializes the Calendar component in theGerman
culture.
import { Calendar } from '@syncfusion/ej2-calendars';
//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'));
L10n.load({
'de': {
'calendar': { today: 'heute' }
}
});
let calendarObject: Calendar = new Calendar({
//sets the locale.
locale: 'de'
});
calendarObject.appendTo('#element');
The following example displays the Calendar in German
culture.
import { Calendar } from '@syncfusion/ej2-calendars';
//import the loadCldr from ej2-base
import { loadCldr, L10n } from '@syncfusion/ej2-base';
//load the CLDR JSON data files.
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);
L10n.load({
'de': {
'calendar': {
today: 'heute'
}
}
});
//creates a calendar with German culture.
let calendarObject: Calendar = new Calendar({ locale: 'de' });
calendarObject.appendTo('#element');

Right-to-left
The Calendar supports right-to-left functionality for languages like Arabic, Hebrew, etc. to display text in the right-to-left direction. Use
enableRtl
property to set the RTL direction.
The following code example initializes the Calendar component in Arabic
culture.
import { Calendar } from '@syncfusion/ej2-calendars';
//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/ar/ca-gregorian.json'),
require('cldr-data/main/ar/numbers.json'));
require('cldr-data/main/ar/timeZoneNames.json'));
L10n.load({
'ar': {
'calendar': {
today: 'اليوم'
}
}
});
let calendarObject: Calendar = new Calendar({
//sets the locale.
locale: 'ar'
});
calendarObject.appendTo('#element');
The following example displays the Calendar in Arabic
culture in the right-to-left direction.
//imports the loadCldr from ej2-base
import { loadCldr, L10n } from '@syncfusion/ej2-base';
import { Calendar } from '@syncfusion/ej2-calendars';
//loads the CLDR data files.
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);
L10n.load({
'ar': {
'calendar': { today: 'اليوم'}
}
});
//creates the calendar with Arabic culture.
let calendarObject: Calendar = new Calendar({
//sets the locale
locale: 'ar',
//sets the enableRtl
enableRtl: true
});
calendarObject.appendTo('#element');
