Frequently Asked Questions

How many hours ahead is BST from CST?

British Summer Time (BST) is 7 hours ahead of Central Standard Time (CST). When it's 6:00 PM BST in London, it's 11:00 AM CST in Chicago, making UK summer time significantly better for transatlantic business coordination than the 6-hour difference with CDT.

What time is it in Chicago when it's 3 PM in London?

When it's 3:00 PM BST in London, it's 8:00 AM CST in Chicago during US winter months. This timing allows UK afternoon meetings to connect perfectly with US morning hours, creating excellent business overlap for November to March coordination when the Central US uses standard time.

What time is it in London when it's 10 AM in Chicago?

When it's 10:00 AM CST in Chicago, it's 5:00 PM BST in London during US winter. This alignment means that US morning business hours correspond to UK evening, making the winter months ideal for UK-US Central region communication, as meetings can run from Chicago morning to London evening.

Which US states use CST and when does daylight saving change it?

CST is used by 20 US states, including Texas, Illinois, Missouri, and parts of Kansas, as well as 3 Canadian provinces from November to March. CST changes to CDT from the second Sunday in March to the first Sunday in November, reducing the BST time difference from 7 to 6 hours during summer.

Do UK and US Central business hours overlap better during CST?

Yes, CST creates better overlap! UK business hours (9 AM-5 PM BST) align with US Central hours (9 AM-5 PM CST) for 6 hours daily during winter (3:00 PM-9:00 PM BST = 8:00 AM-2:00 PM CST). This is one hour better than summer CDT, making November to March optimal for UK-US Central business relationships.

How does CST affect UK to US Central travel planning?

CST makes travel timing more convenient - flights from London departing at 1 PM BST arrive in Chicago around 3-4 PM CST, perfect for same-day meetings. The 7-hour difference (compared to 6 hours in summer) means a more effortless jet lag adjustment and better coordination with US Central business hours for UK travelers during the winter months.

What's the best time for video calls between UK and US Central during winter?

The optimal calling window during CST is 2:00-5:00 PM BST (7:00 AM-10:00 AM CST), allowing UK afternoon hours to align with US Central Time morning productivity. This improved winter timing makes regular collaboration easier than summer months, when the 6-hour CDT difference creates scheduling challenges.

How do I quickly convert BST to CST during US winter?

Subtract 7 hours from UK time to get US Central winter time (6:00 PM London = 11:00 AM Chicago). Remember, CST runs from early November to mid-March, offering better coordination than summer CDT. Most smartphones automatically display the correct US Central Time when you search for "time in Chicago" or "time in Dallas" from the UK.
