تبدیل تاریخ میلادی به شمسی

[nevisande]

آقا سلام
میخواستم ببینم چطور باید تاریخ میلادی زیر رو به شمسی تبدیل کنم؟

var dayarray=new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday")
var montharray=new Array("ژانویه","فوریه","مارس","آوریل","می","ژوئن","جولای","آگوست","سپتامبر","اکتبر","نوامبر","دسامبر")
function getthedate()
{
    var mydate=new Date()
    var year=mydate.getYear()
    if (year < 1000)
        year+=1900
    
    var day=mydate.getDay()
    var month=mydate.getMonth()
    var daym=mydate.getDate()
    if (daym<10)
        daym="0"+daym
    
    var hours=mydate.getHours()
    var minutes=mydate.getMinutes()
    var seconds=mydate.getSeconds()
    var dn=""
    
    
    {
         d = new Date();
         Time24H = new Date();
         Time24H.setTime(d.getTime() + (d.getTimezoneOffset()*60000) + 3600000);
         InternetTime = Math.round((Time24H.getHours()*60+Time24H.getMinutes()) / 1.44);
         if (InternetTime < 10) InternetTime = "00"+InternetTime;
         else if (InternetTime < 100) InternetTime = "0"+InternetTime;
    }
    if (hours==0)
        hours=12
    if (minutes<=9)
        minutes="0"+minutes
    if (seconds<=9)
        seconds="0"+seconds
    //change font size here
    var cdate=daym+" "+montharray[month]+"  "+year+" | "+hours+":"+minutes+":"+seconds+" "+dn+"" | "y"
    if (document.all)
        document.all.clock.innerHTML=cdate
    else if (document.getElementById)
        document.getElementById("clock").innerHTML=cdate
    else
        document.write(cdate)
    }

    if (!document.all&&!document.getElementById)
    getthedate()

function goforit()
{
    if (document.all||document.getElementById)
        setInterval("getthedate()",1000)
}
window.onload=goforit

لطفا یکی کمک کنه
