[javascript] JavaScript how to get tomorrows date in format dd-mm-yy

I am trying to get JavaScript to display tomorrows date in format (dd-mm-yyyy)

I have got this script which displays todays date in format (dd-mm-yyyy)

var currentDate = new Date()
var day = currentDate.getDate()
var month = currentDate.getMonth() + 1
var year = currentDate.getFullYear()
document.write("<b>" + day + "/" + month + "/" + year + "</b>")

Displays: 25/2/2012 (todays date of this post)

But how do I get it to display tomorrows date in the same format i.e. 26/2/2012

I tried this:

var day = currentDate.getDate() + 1

However I could keep +1 and go over 31 obviously there are not >32 days in a month

Been searching for hours but seems to be no answer or solution around this?
