Why Does Illinois Observe Daylight Saving Time?

Daylight Saving Time is observed in Illinois to make better use of daylight. The idea is to shift the clock forward in the spring, giving people an extra hour of daylight in the evening during the warmer months. This was originally promoted during World War I to conserve energy. While the energy-saving benefits are debated today, DST remains in effect across most of the United States, including Illinois.

Examples & Use Cases

Business Example

A Chicago-based company needs to schedule a video conference with a client in Los Angeles. To ensure everyone joins the meeting at the correct time, the company must account for the time difference between Central Time (Illinois) and Pacific Time (Los Angeles). If the meeting is scheduled for 10:00 AM in Los Angeles, it would be 12:00 PM in Illinois during Standard Time and 1:00 PM during Daylight Saving Time.

Travel Example

A family is traveling from New York City to Chicago. They need to adjust their clocks when they arrive in Illinois. During Standard Time, they will set their clocks back one hour. During Daylight Saving Time, they will set their clocks back two hours.

Personal Example

A person in Florida wants to watch a live sporting event in Chicago. They must consider the time difference to tune in at the right time. During Standard Time, if the event starts at 7:00 PM in Chicago, it starts at 8:00 PM in Florida. During Daylight Saving Time, the event starts at 8:00 PM in Florida. — St. Albans, VT Zip Code: Your Complete Guide
