Frequently Asked Questions – London Time Zone & GMT
London uses GMT (Greenwich Mean Time, UTC+0) in winter and BST (British Summer Time, UTC+1) in summer. Clocks go forward on the last Sunday in March and back on the last Sunday in October.
Yes. The UK observes Daylight Saving Time (BST) from the last Sunday in March (clocks go from 01:00 to 02:00) to the last Sunday in October (clocks go from 02:00 back to 01:00). This is synchronised with most of continental Europe on the same dates.
For most of the year, London is 5 hours ahead of New York (GMT vs EST, or BST vs EDT). However, for a short window in spring (when the US has changed its clocks but the UK hasn't yet, or vice versa), the gap can briefly be 4 or 6 hours. Use our live converter above for the exact current difference.
The time difference between London and Sydney varies throughout the year because Australia observes DST in the opposite hemisphere season. In the UK's winter (GMT), Sydney is typically 11 hours ahead (AEDT). In the UK's summer (BST), it narrows to around 9 hours ahead (AEST). The live comparison table above always shows the current accurate difference.
London sits on the Prime Meridian (0° longitude), which passes through the Royal Observatory in Greenwich. At the 1884 International Meridian Conference in Washington, this line was adopted as the global reference. France and other European countries lie to the east and therefore use UTC+1 (CET), but the UK remains on its natural solar time of UTC+0. Brexit did not change this arrangement.
GMT (Greenwich Mean Time) and UTC (Coordinated Universal Time) both represent UTC+0 and are effectively equivalent for everyday use. The technical distinction is that GMT is defined astronomically (based on Earth's rotation), while UTC is based on atomic clocks and is slightly more precise. In practice, for scheduling and daily timekeeping, GMT and UTC can be used interchangeably. Learn more on our GMT vs UTC page.
London has 5 main airports. The closest to the centre is London City (LCY), just 11 km to the east (~22 min on the Elizabeth line). The largest and most international is Heathrow (LHR), 24 km to the west (~45 min). Budget travellers often use Stansted (STN) (Ryanair) or Luton (LTN) (easyJet, Wizz Air).
Summer (June–August) offers the most sunshine and the longest days (sunset after 9 PM in BST), but also peak crowds and higher prices. Spring (April–May) and autumn (September–October) are ideal: mild temperatures of 14–18°C, fewer tourists, and cheaper accommodation. Winter brings festive Christmas markets and dazzling light displays, with temperatures rarely dropping below 0°C.
