Confused with the academic term difference between both hemispheres?

I will start my High School senior year this February. I will be graduating in December and I plan to go to college in the US but I don’t know when I would start applying. I know about early decission/action, regular and rolling applications, but I’m confused about when to start applying? Can I apply for early action November for the fall term of 2017? Is it possible?

I’m from the Southern Hemisphere

For students who plan to start college in August/Sept of 2017:

Rolling admissions typically open sometime in Sept/Oct (varies by uni) 2016
ED/EA deadlines cluster in Oct/Nov of 2016.
RD deadlines cluster around the change of the year 2016/2017
ED II deadlines (there are some unis that offer this) are usually in January.

Hope that helps!
