    Implemented This gadget on my blog.
    works perfectly! highly recommended!

    A small tip:
    This gadget displays the titles of the posts under the calendar.
    In order to remove them, I looked for the lines:
    document.getElementById("cal1Titles").innerHTML += "" + title + "";
    and:
    document.getElementById("cal1Titles").innerHTML = _dayTitles[day];

    and commented them out.

    enjoy this gadget!
