North America

Illinois is a state located in the Midwestern region of the United States. It is bordered by Wisconsin to the north, Iowa to the west, Missouri to the southwest, Kentucky to the south, and Indiana to the east. Illinois also borders Lake Michigan and shares a water border with Michigan in the northwest corner of the state. The state capital of Illinois is Springfield while its largest city is Chicago.

The land area of Illinois covers 57,914 square miles making it the 25th largest state in terms of size. The geography of Illinois is mostly flat plains with some rolling hills and river valleys throughout. The highest point in Illinois is Charles Mound which stands at 1235 feet above sea level while its lowest point lies along Lake Michigan at 579 feet above sea level.

The majority of Illinois lies within two distinct physiographic regions: The Central Lowlands and The Interior Low Plateaus Region. The Central Lowlands are made up mostly of flat plains that were created by glacial deposits from ancient glaciers that once covered much of North America during the last ice age. This region accounts for most of northern and central Illinois including Chicago and its suburbs as well as much of eastern Missouri and western Indiana.

The Interior Low Plateaus Region consists mostly of rolling plateaus that are broken up by deep river valleys including those formed by the Mississippi River, Ohio River, Wabash River, Kaskaskia River and Sangamon River among others. This region encompasses most of southern Illinois including Springfield as well as portions of northwestern Kentucky and southwestern Indiana.

Illinois experiences four distinct seasons with hot humid summers that often reach temperatures over 90 degrees Fahrenheit in July and August while winters can be very cold with temperatures often dipping below 0 degrees Fahrenheit during December and January months. Precipitation levels throughout much of this area average around 40 inches per year with most occurring during spring months between April through June.


Time Zone of Illinois

Illinois is located in the Central Time Zone, which is six hours behind Coordinated Universal Time (UTC). This time zone covers parts of the United States, Canada, and Mexico. The states of Illinois, Indiana, and Wisconsin are all located within this time zone. In addition to these states, the provinces of Manitoba and Ontario in Canada as well as the states of Tamaulipas and Veracruz in Mexico also fall within this time zone.

The Central Time Zone is one hour ahead of the Mountain Time Zone which covers parts of the western United States including Arizona and New Mexico. It is also one hour behind the Eastern Time Zone which covers much of the eastern United States including New York City and Washington D.C.

The Central Time Zone observes daylight saving time (DST) from March through November each year when clocks are moved ahead one hour from standard time to make more efficient use of natural daylight during those months. During DST, clocks are set to UTC-5 instead of UTC-6.

In Illinois, most areas observe Central Standard Time (CST) year-round with no daylight saving time observed since 2007 when a law was passed that abolished it for most areas within this state. However, some counties near Chicago such as Kendall County observe Eastern Standard Time year-round due to their close proximity to Chicago which lies within that particular time zone.

Throughout most parts of Illinois there is an exception for certain businesses that may choose to observe DST depending on their location or type of business they operate such as retail stores or restaurants which may choose to follow a different schedule than others in order to remain competitive with other businesses outside their local area that do observe DST during certain months out of the year.

It’s important for people living or travelling through Illinois to be aware of what time zone they are in so they can plan accordingly for any meetings or appointments they may have while there since some areas may not observe daylight saving time while others do depending on where exactly they are located at any given moment in time.
