The summer Olympics occur every four years. The most recent summer Olympics occurred in 2008, so the next summer Olympics will be in 2012. The 2012 Summer Olympics are scheduled to begin on July 27.
Every 2 years after the summer one so in this case it is in 2012
China, it is already going on.
I believe it was the 30th official games..
it was Atenas 2004 and summer.
