Date picker swapping month and day for Canada users

Hi, we are using datepicker withd efault format mm/dd/yy, for some Canada users it's flipping as dd/mm/yy. Not sure what's causing this to happen. Since they are home computers, hard to track the problem.

Code: <pre>

$(document).ready(function() {

var today = new Date(),

minutes = today.getMinutes(),

previousdate = today.getTime(),

previousdate = previousdate - (today.getHours() * 60 * 60 * 1000) - (today.getMinutes() * 60 * 1000) - (today.getSeconds() * 1000),

onejan = new Date(today.getFullYear(),0,1);

var minDate = today;

var hours = minDate.getHours();

if(minDate.getDay()>=1){

if(hours >= 7 && minutes > 0){

minDate = new Date(minDate.setDate(minDate.getDate() + 7));

}

}

Date.prototype.getWeek = function () { return $.datepicker.iso8601Week(this); }

var pickerOpts = {

showOn: "button",

buttonImage: './images/calendar.gif',

buttonImageOnly: true,

showWeek:true,

minDate: today,

beforeShowDay: function(date)

{

if(date.getWeek()>=1 && date.getWeek()<=23){

return [(date.getDay() == 4), ""];

}else{

return [false,""];

}

}

};

var cal = {

showOn: "button",

buttonImage: './images/calendar.gif',

buttonImageOnly: true

};

var minDefferalDate = new Date();

var minutesDeff = minDefferalDate.getMinutes();

var hoursDeff = minDefferalDate.getHours();

if(minDefferalDate.getDay()==5){

//if(hoursDeff >= 7 && minutesDeff > 17 ){

if(hoursDeff > 5){

minDefferalDate = new Date(minDefferalDate.setDate(minDefferalDate.getDate() + 10));

}

}

var pickerMon = {

showOn: "button",

buttonImage: './images/calendar.gif',

buttonImageOnly: true,

minDate: minDefferalDate,

beforeShowDay: function(date)

{

return [(date.getDay() == 1), ""];

}

maxDate: calendar.newDate(date.getYear()+1, 8, 1),

};

$("#date").datepicker(pickerOpts);

$("#date1").datepicker(pickerMon);

$("#date2").datepicker(pickerMon);

$("#date3").datepicker(pickerMon);

$("#date4").datepicker(pickerMon);

$("#date5").datepicker(pickerMon);

$('#datePicker').datepicker({ minDate: 4,beforeShowDay: $.datepicker.noWeekends });

$("#startDate").datepicker(cal);

$("#endDate").datepicker(cal);

$('#startDate').attr('readonly', true);

$('#endDate').attr('readonly', true);

$(".listItr td:not(:LAST-CHILD)").css({'border' :'1px solid black'});

$("table.gridtable th:not(:LAST-CHILD)").css({ 'border-width': '1px', 'padding': '8px', 'border-style': 'solid', 'border-color': '#666666',

'background-color': '#dedede'});

/*

*/

$('#cid').keypress(function(e) {

var a = [];

var k = e.which;

for (i = 48; i < 58; i++)

a.push(i);

if (!($.inArray(k,a)>=0))

e.preventDefault();

});

});

</pre>
