Best Hours to Schedule DubaiLondon Calls

Dubai's 9:00 AM–6:00 PM GST business day starts when London (GMT) is at 5:00 AM–2:00 PM. The overlap is 9:00 AM–1:00 PM London (1:00–5:00 PM Dubai). After 1 PM London, Dubai approaches end-of-day. Also note Dubai works Sunday–Thursday, not Monday–Friday.

About Dubai (GST)

Dubai (GST, UTC+4) is fixed year-round — no DST. The UAE's working week runs Sunday to Thursday, which adds a scheduling layer beyond the clock difference. Dubai is a major MENA financial hub, with strong ties to London-based banks, asset managers, and professional services firms.

About London (GMT)

London (GMT/BST) is 4 hours behind Dubai in winter. During UK BST, the gap narrows to 3 hours — giving slightly more overlap. For London professionals calling Dubai, the morning (9 AM–1 PM GMT) is the prime window before Dubai enters end-of-day.

How to Avoid DubaiLondon Conversion Mistakes

Use the live clocks and the table for different jobs. The live clocks show the current offset between Dubai and London. The table gives you a stable reference for planning common hours. If the page has more than one table column, pick the column that matches the season or DST state shown in the column label.

Daylight saving is the main trap. Some pairs stay fixed all year, while others move by one hour because only one side changes clocks, or because the two sides change on different dates. That is why this page keeps the daylight saving note near the live clocks and labels alternate table scenarios instead of hiding the offset change in a paragraph.

Always check the calendar date when the converted time lands near midnight. A late evening time in Dubai can become the next day in London, and an early morning time can still be the previous day. If the table marks "next day" or "prev day", include that date shift in the message or calendar invite.

Abbreviations can be ambiguous. ET can mean EST or EDT; London can be GMT or BST; Sydney can be AEST or AEDT. City names and IANA time zones are safer for exact scheduling than abbreviations alone. For recurring meetings, test the same local time once in January and once in July before you lock it in.

For one-off events, enter the exact date and time in the main time zone converter or meeting scheduler if the table does not show your hour. That keeps the answer tied to the correct daylight saving rule instead of a memorized offset.

When you share the result, write both local times in one line: "10:00 AM GST/ converted GMT time." For client calls, flights, webinars, launches, and deadlines, also include the date. The extra wording feels repetitive, but it gives every recipient a second way to catch a timezone mistake before it becomes a missed meeting. It is especially helpful when someone forwards the invite to a third city.
