in-date news items

Hi all,

I'm trying to use a select to get the latest item of news, provided that it's 
within the last X days.  What do I need to add to the where clause for the 
select statement below:

select ndate, nauthor, nheading   from news   order by ndate desc   limit 1
*** where ndate within the last 3 months ******
