<!-- 1 day, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 28 DaySummer, 28 DayWinter, Excess Amount, excess miles................................. -->
		switch (document.date.car.value) {

I'm new to java and have been given the following piece of code to try and fix.

The code is renaming an existing HTML file with the current date but the problem is the date is out by one. I'm aware that in java Jan=0 Feb=1 etc but just dont know enough to know how to fix this...

If I add +1 to getmonth all that happens is the file gets named LEICESTER_DAILY - 24-71-2011 17.20.36 rather than LEICESTER_DAILY - 24-8-2011 17.20.36

Here's the piece of code

Code:

function makePerm() {
var txtFile;
	// Swap the temporary file with the original
	if (fileSys.FileExists(grabParentFolderUrl() + 'tempsave.htm')) {
		txtFile = fileSys.getFile(grabParentFolderUrl() + 'tempsave.htm');
		if (!(txtFile.size == 0)) { // Check file is not empty
			if (fileSys.FileExists(grabParentFolderUrl() + 'LEICESTER_DAILY.htm')) { 
				var today = new Date();
				var timeStamp = today.getDate() + '-' + today.getMonth() + '-' + today.getFullYear() + ' ' + today.getHours() + '.' + today.getMinutes() + '.' + today.getSeconds();
				txtFile = fileSys.getFile(grabParentFolderUrl() + 'LEICESTER_DAILY.htm');
				txtFile.Move(grabParentFolderUrl() + 'LEICESTER_DAILY - ' + timeStamp.toString() + '.htm');
				txtFile = fileSys.getFile(grabParentFolderUrl() + 'tempsave.htm');
				txtFile.Move(grabParentFolderUrl() + 'LEICESTER_DAILY.htm');

I'm trying to make it so that on holidays, my page will say Happy"so and so..." at the top. I only started this 5 minutes ago so that's why it's so under developed. Here's what I have. I'm wanting to know if "today.getMonth.getDate" is valid or would I have to do something else.

function startTime()
{
var today=new Date();
var hol=today.getMonth.getDate()

if (hol==4+1)

p.s I only want the holiday. I already have a clock but I want them to be separate.
