Dubai Stays Put, London Moves
Dubai is UTC+4 all year. London is UTC+0 in winter and UTC+1 in summer, switching on the last Sunday in March (forward) and the last Sunday in October (back), so Dubai leads by 4 hours on GMT and 3 on BST.
Add 4 or 3 hours going east: 1:00 PM in London is 5:00 PM in Dubai in winter and 4:00 PM in summer, so London's afternoon is already Dubai's evening. A call fixed at a Dubai time shifts by an hour on London's clock on those weekends: 3:00 PM in Dubai is 11:00 AM in London on GMT and 12:00 PM on BST.
London Morning, Dubai Afternoon
On 9-to-5 days the overlap is London's morning. In winter, 9:00 AM to 1:00 PM in London is 1:00 PM to 5:00 PM in Dubai, 4 hours. In summer the shared window is 9:00 AM to 2:00 PM in London, 12:00 PM to 5:00 PM in Dubai, an hour longer. Dubai's 5 PM close is the limit in both seasons.

Each row is an hour of the London day. A check mark means both cities are inside a 9 AM to 5 PM working day at that moment.
- GMT → GST: 4 hours shared, 9:00 AM to 1:00 PM London time.
- BST → GST: 5 hours shared, 9:00 AM to 2:00 PM London time.
Dubai Fridays
Federal offices in the UAE moved to a Monday to Friday week on January 1, 2022, and Friday ends at noon. Companies set their own hours, but if the Dubai side keeps a short Friday, noon in Dubai is 8:00 AM in London on GMT and 9:00 AM on BST, so a Friday call has to be early in the London day.
A Weekly 10 AM Call From London
A London team that calls Dubai at 10:00 AM reaches 2:00 PM on GMT and 1:00 PM on BST. A 12:00 PM start is 4:00 PM on GMT and 3:00 PM on BST, already the Dubai late afternoon.
If Dubai hosts at 2:00 PM, London joins at 10:00 AM on GMT and 11:00 AM on BST. A series fixed in Dubai time drifts on the London calendar in March and October.
