Calculating months 2

[TheConeHead]

I have two date objects. I need to determines how many months are between these two dates. Meaning if it was may 31 and June 1, I would get back 2 or if it was December 5 2006 and June 23 2007 - I would get back 7.

How can this be done?

Hmmm, my issue breaks down to the fact that getTime() won't due me any good (I don't think...) since given May 31 and June 1 - I want 2 returned and breaking it down to ms will just show me two days... and not two months... thanks, though...

Do a little adaptation, mate

<script type="text/javascript">

//Set the two dates
today=new Date()
var christmas=new Date(today.getFullYear(), 11, 25) //Month is 0-11 in JavaScript
if (today.getMonth()==11 && today.getDate()>25) //if Christmas has passed already
christmas.setFullYear(christmas.getFullYear()+1) //calculate next year's Christmas
//Set 1 day in milliseconds
var one_month=1000*60*60*24*30

//Calculate difference btw the two dates, and convert to months
document.write(Math.ceil((christmas.getTime()-today.getTime())/(one_month))+
" moths left until Christmas!")

</script>

Cheers,
Dian
