By Michael Ferguson

If you are planning a trip from London to Chicago or vice versa, it is important to know the time difference between the two cities. Since both cities are located in different time zones, it can be confusing to determine what the standard time in Chicago would be when it is 12 noon in London. In this article, we will explore this topic and provide you with a clear understanding of the time difference between these two cities.

Time Zones

To understand the time difference between London and Chicago, it is essential to have a basic understanding of time zones. A time zone is a region of the Earth where all clocks are set to the same standard time. There are 24 different time zones around the world, and each one has a unique offset from Coordinated Universal Time (UTC).

London Time Zone

London is located in the United Kingdom and follows Greenwich Mean Time (GMT). GMT is also known as Universal Time Coordinated (UTC+0). This means that when it is 12 noon in London, it is 12:00 PM UTC.

Chicago Time Zone

Chicago is located in the United States and follows Central Standard Time (CST). CST is six hours behind GMT or UTC-6. This means that when it is 12 noon UTC, it will be 6:00 AM CST.

Calculating Time Difference

To calculate the time difference between London and Chicago, we need to subtract six hours from Greenwich Mean Time (GMT). So when it’s 12 noon in London, we subtract six hours from GMT to get 6:00 AM. Therefore, if it’s 12 noon in London, then it will be 6:00 AM CST or Central Standard Time.

Conclusion

Knowing the time difference between London and Chicago is essential if you are planning a trip or need to communicate with someone in the other city. When it’s 12 noon in London, it will be 6:00 AM Central Standard Time (CST) in Chicago. This six-hour time difference is important to keep in mind when scheduling meetings, flights, or any other activities that require coordination between the two cities.
