Cara membuat jam analog

saya akan berbagi mengenai percobaan saya membuat jam analog menggunakan
html dan javascript, berikut cara singkatnya heheheehehehehhe
buat kritik kirim ke yujimaarif.ym@gmail.com
pertama buka notepad
dan tulis kode ini:

<html> <head> <title>jam analog</title> <br />
</head> <br />
<body> <br />
<script>
var dt=new Date()
var day = dt.getDate()
var month = ['January','February','March','April','May','June','July','August','September','October','November','December'];
var month=dt.getMonth();
month++;
var year = dt.getFullYear();
document.write(day+"/");
document.write(month+"/");
document.write(year+"<br />");
</script><br />
<canvas id="jam" width="100" height="100"left="200"top="200"></canvas> <br />
<script type="text/javascript"> 
window.onload = function() 
{ 
function gambar() 
{ 
var ctx = document.getElementById('jam').getContext('2d'); 
ctx.strokeStyle = "(1, 2, 3,4,5,6,7,8,9,10,11,12)"
ctx.clearRect(0, 0, 100, 100); 
ctx.beginPath(); 
ctx.lineWidth = 4; 
ctx.arc(360, 270, 90, 180, Math.PI * 8, true) 
ctx.stroke();
var i; for(i=0; i < 360; i+=5) 
{ 
ctx.lineWidth = ((i % 30)==0)?6:1; 
ctx.strokeStyle = ((i % 60)==0)?"rgb(200,11,20)":"rgb(4,5,4)"; 
var q = i * Math.PI / 180; 
ctx.beginPath(); 
ctx.moveTo(50+(180 * Math.sin(q)), 90+(180 * Math.cos(q))); 
ctx.lineTo(50+((((i % 270)==0)?40:40) * Math.sin(q)),
 50+((((i % 90)==0)?40:40) * Math.cos(q))); 
ctx.closePath(); 
ctx.stroke();
} 
ctx.strokeStyle = "rgba(32, 34, 33, 6.9)"; 
// jam
 var h = new Date(); 
 var j = (h.getHours() % 12) + (h.getMinutes() / 60); 
 ctx.lineWidth = 4; 
 ctx.beginPath(); 
 ctx.moveTo(50+(25 * Math.sin(j * 30 * Math.PI / 180)), 
 50+(-25 * Math.cos(j * 30 * Math.PI / 180))); 
 ctx.lineTo(50+(5 * Math.sin((j+6) * 30 * Math.PI / 180)), 
 50+(-5 * Math.cos((j+6) * 30 * Math.PI / 180))); 
 ctx.closePath(); ctx.stroke(); 
 //minute 
 var m = h.getMinutes() + (h.getSeconds() / 60); 
 ctx.strokeStyle = "rgba(32, 32, 62, 1.8)"; 
 ctx.lineWidth = 2; 
 ctx.beginPath(); 
 ctx.moveTo(50+(29 * Math.sin(m * 6 * Math.PI / 180)),
 50+(-29 * Math.cos(m * 6 * Math.PI / 180))); 
 ctx.lineTo(50+(3 * Math.sin((m+30) * 6 * Math.PI / 180)),
 50+(-3 * Math.cos((m+30) * 6 * Math.PI / 180))); 
 ctx.closePath(); 
 ctx.stroke(); 
 //detik
 var d = h.getSeconds()+ (h.getMilliseconds() / 1000);
 ctx.strokeStyle = "rgba(43, 55, 1, 0.7)";
 ctx.lineWidth = 1; 
 ctx.beginPath(); 
 ctx.moveTo(50+(30 * Math.sin(d * 6 * Math.PI / 180)), 
 50+(-30 * Math.cos(d * 6 * Math.PI / 180))); 
 ctx.lineTo(50+(10 * Math.sin((d+30) * 6 * Math.PI / 180)), 
 50+(-10 * Math.cos((d+30) * 6 * Math.PI / 180)));
 ctx.closePath(); ctx.stroke(); } setInterval(gambar, 2000); }
