Javascript returning month as 9 where it is 10

Question

I'm building today's date using a onclick event in JavaScript. When i set the .value property with:

var now = new Date;
...Value = now.getMonth() + "/" + now.getDate() + "/" + now.getYear();

this produces: 9/9/2009 I am expecting: 10/9/2009

This happens in both IE and Firefox. The system time on my computer is correct. Any ideas?

Answer 1

getMonth() starts at 0.

Answer 2

It's zero-based. January is month 0.
