Довольно просто с JS -
var d_names = new Array("sun", "mon", "tue", "wed", "thu", "fri", "sat");
var d = new Date();
var curr_date = d.getDate();
var curr_month = d.getMonth();
curr_month++;
var curr_year = d.getFullYear();
document.write(d_names[curr_day] + ", " +curr_month + "/" + curr_date + "/" + curr_year);
и Боб твой дядя ...
