UK time zone: GMT in winter, BST in summer
The United Kingdom uses a single time zone. London is UTC+0 (Greenwich Mean Time) from late October to late March and UTC+1 (British Summer Time) from late March to late October. There is no regional time-zone split inside the UK, so Manchester, Birmingham, Edinburgh, Cardiff, and Belfast all change clocks on the same date.
Most UK offices work roughly 9:00 AM to 5:30 PM, with lunch somewhere between 12:00 and 2:00 PM. London financial and professional-services teams often start earlier and finish later, but a 9:00-5:30 default is the safest assumption for a first meeting.
US-UK meeting windows that survive DST
With standard 9-to-5 schedules, the reliable New York-London window is 9:00 AM-12:00 PM Eastern, which is 2:00-5:00 PM in London. That is a three-hour overlap, and the middle of it - around 10:00 AM ET / 3:00 PM London - is the least fragile slot for a 60-minute call.
For two mismatch weeks each year, the US changes clocks before the UK. In 2027 the US moves on March 14 and the UK on March 28, then the UK moves on October 31 and the US on November 7. During March 14-28 and October 31-November 7, New York is only four hours behind London, so the same meeting shifts an hour later in London. Recheck recurring invites on those dates.
UK-India and UK-Australia corridors
The UK-India corridor is one of the easiest long-haul schedules. London mornings land in Delhi's afternoon: 9:00 AM-12:00 PM London is 2:30-5:30 PM IST in winter and 1:30-4:30 PM IST in summer. India never changes clocks, so only the UK date matters.
The UK-Australia corridor has no strict 9-to-5 overlap. A practical handover is 8:00-10:00 AM London, which is 7:00-9:00 PM in Sydney during Australian summer time and 6:00-8:00 PM during Australian winter. Keep it short, rotate the late end, and do not make it the only collaboration window.

FAQ
Frequently asked questions.
What is the best time to meet between the UK and the US?
With 9-to-5 schedules, the best US-UK window is 9:00 AM-12:00 PM Eastern, which is 2:00-5:00 PM in London. Around 10:00 AM ET / 3:00 PM London is the safest single slot. During the March 14-28 and October 31-November 7, 2027 mismatch weeks, shift the meeting an hour later in London.
Does the UK observe daylight saving in 2027?
Yes. UK clocks go forward on Sunday, March 28, 2027 and back on Sunday, October 31, 2027. London is UTC+1 (BST) between those dates and UTC+0 (GMT) for the rest of the year.
What is the difference between GMT and BST?
GMT is Greenwich Mean Time, UTC+0, used in winter. BST is British Summer Time, UTC+1, used from late March to late October. When scheduling, GMT and BST are not interchangeable - check which one applies on your meeting date.
How many hours ahead is London than New York?
London is normally five hours ahead of New York. During the US-UK DST mismatch weeks - March 14-28 and October 31-November 7, 2027 - London is only four hours ahead because the two countries change clocks on different dates.
Can I plan UK meetings with India and Australia?
Yes. UK-India is comfortable: 9:00 AM-12:00 PM London is 2:30-5:30 PM IST in winter and 1:30-4:30 PM IST in summer. UK-Australia has no strict 9-to-5 overlap; the practical handover is 8:00-10:00 AM London, which is 6:00-9:00 PM in Sydney depending on the season.
