Your function works fine for me when called correctly: (IE6 & Firefox
1.5)

<input type="text" id="timetest" onblur="doDateCheckNow(this);">

function doDateCheckNow(source) {
        var oDate = source; //dd/mm/yyyy
        var arrDate = oDate.value.split("/");
        var useDate = new Date(arrDate[2], arrDate[1]-1, arrDate[0]);
//yyyy/mm/dd
        var today = new Date();

        if (useDate <= today)
        {
                alert("true");
        }
        else
        {
                alert("false");
        }

}

How are you calling your function? Try putting some alerts after each
variable is set/changes, to make sure your getting the text data from
your fields.

I don't know that this has anything to do with ASP...
