Datepicker- Week starts on Sunday with Week number

Question

How do I display week starts from Sunday in datepicker along with week numbers.

eg: I need Week starting from 12/03/23(Sunday) should display week number 11 instead of 10. Any help appreciated. thanks

my code:-

$(document).ready(function() {
  $('.date-picker').datepicker({
    showWeek: true,
    firstDay: 0,
    changeMonth: true,
    changeYear: true,
    showButtonPanel: false,
    dateFormat: 'dd/mm/yy',
    autoclose: true,
  });
});

<input name="sel-date" id="sel-date" class="date-picker" value="<?= $week_start ?>">

You can use the calculateWeek property from the datepicker also you can use beforeShowDay to disable the dates like i have done in the snippet..

let me know

Date Picker on input field:

$(function(){
 $('.date-picker').datepicker({   
   showWeek: true,      
   firstDay: 0,
   changeMonth: true,
   changeYear: true,
   showButtonPanel: false,
   dateFormat: 'dd/mm/yy',
   autoclose: true,
   calculateWeek: date => $.datepicker.iso8601Week(new Date(date)) + 1,
   beforeShowDay: function(date) {
     return [date.getDay() === 0,''];
   },  
 });
});

#ui-datepicker-div { font-size: 12px; } 

Date Picker on input field: <input name="sel-date" id="sel-date" class="date-picker" value="12/03/2023">
