I am using datepicker and I want it to work in Hebrew.
I found this: https://jqueryui.com/datepicker/#localization
but I don't want the user to choose a language. I want ths datepicker to work only in Hebrew.
How can I do that?
I tried this:

 $.datepicker.setDefaults($.datepicker.regional['he']);

i got an answer from Sooriya Dasanayake but now I am trying to add date range and that doesn't work:

 from = $( "#from" ).datepicker(
 defaultDate: "+4w",
 changeMonth: true,
 numberOfMonths: 3,
 showButtonPanel: true,
 showOn: "button",
 showAnim:"blind",
 onSelect: function( selectedDate ) 
 $( "#from" ).datepicker( $.datepicker.regional[ "en-GB" ] );
 $( "#locale" ).change(function() 
 $( "#from" ).datepicker( "option",
 $.datepicker.regional[ $( this ).val() ] );
 )
 
 )
 .on( "change", function() 
 to.datepicker( "option", "minDate", getDate( this ) );
 ),
 to = $( "#to" ).datepicker(
 changeMonth: true,
 numberOfMonths: 3,
 showButtonPanel: true,
 showOn: "button",
 showAnim:"blind",
 onSelect: function( selectedDate ) 
 $( "#to" ).datepicker( $.datepicker.regional[ "en-GB" ] );
 $( "#locale" ).change(function() 
 $( "#to" ).datepicker( "option",
 $.datepicker.regional[ $( this ).val() ] );
 )
 
 )
 .on( "change", function() 
 from.datepicker( "option", "maxDate", getDate( this ) );
 );

 function getDate( element ) 
 var date;
 try 
 date = $.datepicker.parseDate( dateFormat, element.value );
 catch( error ) 
 date = null;
 

 return date;
 

});

Try this..

 jQuery(function($)
 $.datepicker.regional['he'] = 
 closeText: 'סגור',
 prevText: '<הקודם',
 nextText: 'הבא>',
 currentText: 'היום',
 monthNames: ['ינואר','פברואר','מרץ','אפריל','מאי','יוני',
 'יולי','אוגוסט','ספטמבר','אוקטובר','נובמבר','דצמבר'],
 monthNamesShort: ['ינו','פבר','מרץ','אפר','מאי','יוני',
 'יולי','אוג','ספט','אוק','נוב','דצמ'],
 dayNames: ['ראשון','שני','שלישי','רביעי','חמישי','שישי','שבת'],
 dayNamesShort: ['א'','ב'','ג'','ד'','ה'','ו'','שבת'],
 dayNamesMin: ['א'','ב'','ג'','ד'','ה'','ו'','שבת'],
 weekHeader: 'Wk',
 dateFormat: 'dd/mm/yy',
 firstDay: 0,
 isRTL: true,
 showMonthAfterYear: false,
 yearSuffix: '';
 $.datepicker.setDefaults($.datepicker.regional['he']);
);
