<?if($_YAHOO$)?>... <?endif?>

и после $_AOL$ вставляем:

Code
<?if($_YAHOO$)?>
$_YAHOO$
<?endif?>) <script type="text/javascript">
today = new Date();
BigDay = new Date("$_YAHOO$")
msPerDay = 24 * 60 * 60 * 1000;
timeLeft = (BigDay.getTime() - today.getTime());
e_daysLeft = timeLeft / msPerDay;
daysLeft = Math.floor(e_daysLeft);
e_hrsLeft = (e_daysLeft - daysLeft)*24;
hrsLeft = Math.floor(e_hrsLeft);
minsLeft = Math.floor((e_hrsLeft - hrsLeft)*60);
if(daysLeft>0){
document.write( "Осталось <b>"+daysLeft+"</b> дней(дня).");}
else{document.write('Сегодня $_AOL$');}
</script>
