Scheduling guide
Dubai does not observe daylight saving, so the gap with London moves with the UK clock: 4 hours in winter (GMT vs Gulf Standard Time) and 3 hours in summer (BST vs GST). The workday overlap is generous either way: 9:00 AM to 2:00 PM London in winter (1:00 to 6:00 PM Dubai), stretching to 9:00 AM to 3:00 PM London in summer (12:00 to 6:00 PM Dubai).
One cultural note matters more than the math: the UAE workweek runs Monday to Friday, but Friday afternoons are quiet and many people leave early. Schedule important Dubai calls Monday to Thursday, and prefer mornings London time so Dubai colleagues are not pushed into the evening.
The sweet spot is 10:00 to 11:00 AM London, which is early afternoon in Dubai year-round. Avoid booking the last overlap hour on Fridays, and remember Ramadan shifts working hours across the Gulf: during the holy month, aim for the earliest shared hour of the day.
