When do you have the Olympics?

Back in the old days the Winter & Summer Olympics were both in the same year, and 4 years apart. Now-a-days, they switch every 2 years from Summer, to Winter! So, for example in 2008 we had the Summer Olympics in Beijing, and 2 years later we had the 2010 Winter Olympics in Vancouver! :) Next we will be having the Summer Olympics of 2012 in London! I am not certain when the Olympics will be coming to your country
