Countdown problem to date next year!

I have followed the tutorial (http://www.kirupa.com/developer/mx/countdown2.htm) to countdown to Christmas day. However I want to count down to a date in Feb next year.

How could I modify the code I have already (posted below) to be able to do this. I am fairly new to flash programming so am unaware of the syntax.

// first get this current year so this example
// remains valid for some time to come
currentDate = new Date();
thisYear = currentDate.getFullYear();
// define the event date counting down to
// this is constant so it won’t need to be
// calculated in the onEnterFrame function below
// currently counting down 'til christmas of 2003
// Date( year, month-1, date [, hour [, minute [, second [, millisecond]]]])
eventDate = new Date(thisYear, 01, 01);
eventMillisecs = eventDate.getTime();

Any help is greatly appreciated, thanks
