//**Updated Feb 23rd, 08): Adds ability for menu to revert back to default selected tab when mouse moves out of menu



//Only 2 configuration variables below:

function writeCurrentDate()

{

today=new Date(); // Initialize Date in raw form

date=today.getDate(); // Get the numerical date

year=today.getYear(); // Get the year

day = today.getDay(); // Get the day in number form (0,1,2,3,etc.)

month=today.getMonth()+1; // Get the month



// Make day number value correspond to actual day name

var dayName=new Array(7)

dayName[0]="Chç Nh­t";

dayName[1]="Thé Hai";

dayName[2]="Thé Ba";

dayName[3]="Thé T°
";

dayName[4]="Thé N
m";

dayName[5]="Thé Sáu";

dayName[6]="Thé B©y";



// Add suffix to date (1st, 2nd, 4th, etc.)

if (date==1) suffix=("st");

else if (date==2) suffix=("nd");

else if (date==3) suffix=("rd");

else if (date==21) suffix=("st");

else if (date==22) suffix=("nd");

else if (date==23) suffix=("rd");

else if (date==31) suffix=("st");
