About Chicago
Chicago is the largest city in Illinois and the main economic centre of the American Midwest. It is home to major futures and options exchanges, O'Hare, one of the busiest airports in the United States, and a skyline that shaped modern architecture. Visitors know it for its lakefront on Lake Michigan, museums, blues and jazz, and deep-dish pizza.
Chicago follows Central Time: Central Standard Time (UTC-6) in winter and Central Daylight Time (UTC-5) in summer. It sits one hour behind New York and two hours ahead of Los Angeles all year round. The same zone covers much of the central United States, including Dallas, Houston and Nashville, so many national business calls are pitched around Central and Eastern hours.
