I have been using the javascript below on a web page since last August to
show the "Site updated" month only minus a month, which has been very
successful, but January is showing a "undefined 2004" message.
Help much appreciated

Arrays start from 0, not 1. You only need an array to hold 12 items, and
you need to number them from 0. At the moment, you are trying to write out
the string in m[0], which you haven't assigned to anything.

but January is showing a "undefined 2004" message.
<<<var m=new Array(13);var n=new Date()
m[1]="Site updated January";m[2]="Site updated February";m[3]="Site updated
March";m[4]="Site updated April";m[5]="Site updated May";m[6]="Site updated
June";
m[7]="Site updated July";m[8]="Site updated August";m[9]="Site updated
September";m[10]="Site updated October";m[11]="Site updated
November";m[12]="Site updated December"
document.write(m[n.getMonth()+0]+" "+n.getFullYear())>>>
getMonth returns the month number starting with 0 for January and ending with
11 for December. Your table has 1=>January, so it gives the previous month.
That means that you can change
m[12]="Site updated December"
to
m[0]="Site updated December"
and it will work for the month. The year from getFullYear is the current
one, so you will get December 2004 if that is all you do.
I recommend the following instead:
---
var monthName = [
"January","February","March","April","May","June", "July",
"August","September","October","November","Decembe r"];
var now = new Date();
now.setDate(1);
now.setMonth(now.getMonth()-1);
document.write("Site updated ",
monthName(now.getMonth()),
" ",now.getFullYear());
---
We set the date back by one month, so the getMonth and getFullYear
refer to the same date. Setting the month to -1 will give December
of the previous year.
I set the date to the 1st to avoid problems when changing month.
Otherwise, setting the month back by one on the 31th of March would
give the 31th of February, which is normalized to give the 3rd of
March.

var m = new Array(11);
Why "11". You create an array with 11 empty slots, then put 12
elements into it. There is no need for that 11 at all.
m[0] = "January";
.... m[11] = "December"
It is shorter to just write:
var m = new Array("January","February", .... ,"December");
(even shorter to write
var m = ["January",...,"December"];
and it will only fail in browsers older than Netscape 4).

Have you considered the simple and honest approach of typing the correct
date when the site is actually updated?
As it is, your approach of giving an automated lie implies that nothing

First thing: It's Javascript, not Java. Java is a completely different
language.
And please don't top post.
There is a bug in the code, so no wonder it's not working. Here
is a fixed version:
<script type="text/javascript">
var monthName = [
"January","February","March","April","May","June", "July",
"August","September","October","November","Decembe r"];
var now = new Date();
now.setMonth(now.getMonth()-1,1);
document.write("Site updated ",
monthName[now.getMonth()],
" ",now.getFullYear());
</script>
(the square brackets after "monthName" had been replaced by parentheses)

Why "11". You create an array with 11 empty slots, [...]
Or an array with 1 non-empty slot containing a literal 11.
Depends on the ECMAScript implementation, so array literals
are the better way if the first element yields `true' for
!isNaN(...).
