http://www.graduateguide.com/articles.asp?rcatid=17 This site has all the dates for the various types of GRE 2008 tests for everything from Law School to Teaching, Computers, Foreign Language, and everything else.  You did not say which field of study you were looking for, and this list is all-inclusive.  Medical, Dental and Optometry are listed as well if you just keep scrolling down the page.  This site I believe has information on the locations that address where to register, as well as when: www.ets.org/Media/Tests/GR.  Taking the GRE’s involves a lot of hard work and dedication and I wish you good luck with your test.
