change lunch menu each day for a two week period, then start over from the beginning

So, I need to create a cycle of a 14 day menu, (week1_1-7.txt and week2_1-7.txt).

CODE:

----------------------------------------------------------------------------------------------------------------------------------------

function isEvenWeek(now, startDate) {

  var weeks = 604800000; // one week in milliseconds. 
  return Math.floor((now - startDate) / weeks) % 2 == 0;
}

// a monday 
var startDate = new Date(2009, 8, 31);
var now = new Date();

var src = "";
if (isEvenWeek(startDate, now)) {
  src = "week1";
} else {
  src = "week2";
}

----------------------------------------------------------------------------------------------------------------------------------------

This code above I got from a guy who works with javascript and, Im sure it works, but I want to work completely in Flash.

Does anyone knows how to do? I've managed to get an external .txt-file to work properly, but not in this variable day/week-way?

It's a lunch menu which changes everyday for two weeks, then start over from week1_1.txt.

Thank you, thank you, thank you for your help!
