Show div based on today's date

[inko9nito]

I have this script that I got from some site. When you click on a link tied to a div it hides all other divs and displays just that one. Well, that works, but I want it to display one of the divs on page load based on today's date.

For example, it will display the "summer" div if today's date is anywhere between June 1 and August 31. When links to other divs are clicked that div will disappear and other ones will appear in its place. Anyway, here's the code, and I don't know anything about javascript so I have no idea where to even start editing it. Please help

<script type="text/javascript">
<!-- Layer Show/Hide Script
last=""
function changeDiv(the_div,the_change)
{
	var the_style = getStyleObject(the_div);
	
	if (the_style != false)
	{
		the_style.display = "block"
	
		if(last!="")
		{
			last.display = "none"
		}
	}
	
	last=the_style
}
	
function getStyleObject(objectId) 
{
	if (document.getElementById && document.getElementById(objectId)) 
	{
		return document.getElementById(objectId).style;
	} 
	
	else if (document.all && document.all(objectId)) 
	{
		return document.all(objectId).style;
	} 
	
	else 
	{
		return false;
	}
}

I like answering my own questions... If anyone is interested here's the solution:

<script type="text/javascript">
function addLoadEvent(func) 
{
    var oldonload = window.onload;
    if (typeof window.onload != 'function') 
	{
        window.onload = func;
    } 
	
	else 
	{
        window.onload = function() 
		{
            if (oldonload) 
			{
                oldonload();
            }
            func();
        }
    }
}

addLoadEvent(function() 
{
        var today = new Date();
	var month = today.getMonth()+1;
	
	if(month >= 3 && month <=5)
	changeDiv('spring');
	
	else if(month >=6 && month <=8)
	changeDiv('summer');
	
	else if(month >= 9 && month <=11)
	changeDiv('fall');

	else if(month <=2 || month == 12)
	changeDiv('winter');
})
</script>

I added 1 to "month" because it starts with 0 and it was easier to keep track of them if they started with 1.
