See both clocks side by side, why the gap only ever shifts on London's side, and the best overlap window for calls." --- [Home](https://watchtimeonline.com/) / [Local Zone Time](https://watchtimeonline.com/tools/world-clock.html) / London vs Dubai # London vs Dubai Time Difference Dubai runs three to four hours ahead of London year-round — and since Dubai's own clock never changes, every bit of seasonal drift in this pairing comes from London alone. London --:--:-- Europe/London – gap Dubai --:--:-- Asia/Dubai Calculating the live gap… London zone GMT / BST · Europe/London Dubai zone Gulf Standard Time · Asia/Dubai Typical gap 3-4 hours · Dubai ahead Gap changes Calculating… ## A workweek redesigned around this exact gap For decades the UAE ran a Sunday-to-Thursday workweek, following the Islamic tradition of Friday as a day of rest. That meant Dubai's business week and London's business week only overlapped on three days — Sunday and Monday were a working day in Dubai but a weekend or Monday-start in London, creating a standing mismatch for anyone coordinating between the two. In January 2022, the UAE government switched the national workweek to Monday through Friday, with a shortened half-day on Friday, citing better alignment with global markets as a specific goal. It's a rare case of a country adjusting its calendar, not its clock, to close a scheduling gap with cities like London. ## The bridge between two trading days Dubai's fixed UTC+4 offset puts it in an unusually convenient spot: close enough to London to share a real afternoon overlap, and close enough to Asian financial centers further east to bridge toward their morning. That positioning is a deliberate part of Dubai's pitch as a financial hub — the Dubai International Financial Centre operates on a schedule designed to catch the tail end of Asian trading and the start of the European day. **Trivia:** Because Dubai's clock never moves, the entire year-to-year variation in this pairing's gap comes from London alone — a clean four-hours-in-winter, three-hours-in-summer pattern with no messy overlap weeks. ## Best time to call, hour by hour The table below runs through a full London day and shows the matching Dubai time for each hour, with the rows where both cities fall inside a typical 9:00–17:00 workday highlighted. | London time | Dubai time | Both in business hours? | | --- | --- | --- | | Calculating… | | | For most of the year that leaves a solid stretch from about 9:00 a.m. to 1:00 p.m. in London (1:00 p.m. to 5:00 p.m. in Dubai) when both cities are in the office at once — one of the more generous overlaps on this site. London DST starts – Dubai DST starts – London DST ends – Dubai DST ends – **How we calculate this page:** both live clocks, the current gap, the DST transition dates, and the hour-by-hour overlap table are all computed directly from the IANA *Europe/London* and *Asia/Dubai* time zone data via your browser on every page load — nothing here is a fixed, hard-coded figure. ## Frequently asked questions ### What is the time difference between London and Dubai? Four hours during London's winter (GMT) and three hours during London's summer (British Summer Time), with Dubai always ahead. Dubai's own clock never changes. ### Does Dubai observe daylight saving time? No. The United Arab Emirates fixed its clock at UTC+4 decades ago and has not observed daylight saving since. London is the only side of this pairing whose clock shifts. ### Why did the UAE change its official workweek in 2022? In January 2022 the UAE government moved the national workweek from Sunday-through-Thursday to Monday-through-Friday, with a shortened half-day on Friday, explicitly to align its business week more closely with the rest of the world — including major partners like the UK — and make cross-border scheduling simpler. ### What is the best time to schedule a call between London and Dubai? Roughly 9:00 a.m. to 1:00 p.m. in London, which lands at 1:00 p.m. to 5:00 p.m. in Dubai most of the year. That four-hour stretch covers the whole of Dubai's afternoon and London's late morning simultaneously. ### Why is Dubai an important scheduling bridge between Europe and Asia? Dubai's fixed UTC+4 offset sits almost exactly halfway between London and financial centers further east like Singapore or Hong Kong, which is part of why Dubai International Financial Centre markets itself as a bridge between European and Asian trading hours. ### How do I convert London time to Dubai time? Add four hours to London time during GMT (winter), or three hours during British Summer Time.
