The next millennium is just around the corner, and so is its nightmare -- the Y2K bug. Are you prepared? JavaScript's getYear() method is JavaScript's only connection to the Y2K problem. We won't discuss the operation of this method on different browsers, but we'll show you how to overcome the problem. Take a look at the following script:

var now = new Date();
var year = now.getYear();
year += (year < 1900) ? 1900 : 0;

At the end of this code segment, the year variable holds the current year in the four-digit convention. For more information, read The Year 2000, our in-depth article about Y2K issues in JavaScript.
