Frequently Asked Questions

How many hours ahead is BST from EST?

British Summer Time (BST) is 6 hours ahead of Eastern Standard Time (EST) during the brief overlap period. However, this is rare since BST (summer) and EST (winter) are typically not concurrent. Most of the year, you'll convert BST to EDT (5-hour difference) or GMT to EST (5-hour difference).

What time is it in New York when it's 2 PM in London?

During summer months, 2:00 PM BST in London is 9:00 AM EDT in New York. During winter, when London is on GMT, 2:00 PM London equals 9:00 AM EST in New York. Due to coordinated daylight saving changes, the time difference remains consistent at 5 hours throughout most of the year.

What time is it in London when it's 9 AM in New York?

When it's 9:00 AM EDT in New York, it's 2:00 PM BST in London during summer. When it's 9:00 AM EST in New York (winter), it's 2:00 PM GMT in London. This 5-hour difference makes morning meetings in New York perfect for afternoon meetings in London.

Why does the UK-US time difference sometimes change between 4, 5, and 6 hours?

The time difference varies due to different daylight saving schedules. Most of the year, it's 5 hours (BST to EDT or GMT to EST). Briefly in March, it becomes 4 hours when the US switches to daylight saving before the UK. In late October/early November, it can be 6 hours when the UK returns to GMT before the US switches back to EST.

Do London and New York business hours overlap for international meetings?

Yes, there's a perfect 4-hour overlap! London business hours (9 AM-5 PM) align with New York morning hours (4 AM-12 PM local time). The practical overlap for meetings is 2-6 PM London time, which equals 9 AM-1 PM New York time. This makes UK-US collaboration much easier than with West Coast time zones.

What's the best time for business meetings between London and New York?

The optimal meeting window is 9:00 AM-1:00 PM EST/EDT (New York time), which equals 2:00 PM-6:00 PM BST/GMT (London time). This allows New York morning business hours to overlap with London's afternoon hours. Avoid scheduling before 9 AM New York time (too early) or after 1 PM New York time (evening in London).

How does the 5-hour time difference affect travel planning between UK and US East Coast?

The 5-hour difference means eastbound flights (US to UK) arrive the next calendar day, while westbound flights (UK to US) can arrive earlier the same day due to "gaining time." For jet lag recovery, UK to US travel is generally easier. When booking connecting flights, consider the time change - a 3 PM departure from London arrives at 6 PM local time in New York.

How do I quickly convert BST/GMT to EST/EDT on my phone?

Add "New York" to your phone's world clock widget - it automatically shows the correct EST or EDT. For iPhone, use Control Center or ask Siri, "What time is it in New York?" Add "New York, USA" to Google Clock or visit iformat.io for quick conversion.
