Change key frame depending on dates

Hi there,
Quite simply I need a piece of code which jumps to a certain frame based on the actual dates below.

1-4[SUP]rd Dec[/SUP] - gotoAndStop(1);
5[SUP]th Dec [/SUP] - gotoAndStop(2);
6-7[SUP]th Dec[/SUP] - gotoAndStop(3);
8[SUP]th Dec[/SUP] - gotoAndStop(4);

I have found bits of code which allows you to specify which days, but not dates. My actionscript is very beginner so I can’t work out what to do.

THis forum has always been a real help to me so thanks in advance.

Many thanks.
