I know that everynow and then there's a weekend of free Xbox Live, but is there a decent website I can check to know in advance when they are coming, and if applicable, what region the live weekend is for? I missed out on one in.. June or July I think, and I don't want to miss anymore.

that would be helpful anyone know if there is a site like that

majornelson.com

usually tells well in advance atleast most of the time. Sometimes new about it atleast a month in advance.
