I like image version best:
cal.png

With much less CSS:

/*------- CALENDAR ------- */

.cal {
    float: left;
    width: 63px;
    height: 72px;
    margin-top: -6px;
    text-align: top;
    text-align: center;
    background-image:url('http://whanethewhip.wdfiles.com/local--files/theme/cal.png');
    background-position:center;
}
