Understanding the EST to GMT Time Difference
The standard difference between EST and GMT is +5 hours. EST to GMT is the key conversion for US–UK business coordination. New York and London are two of the world's largest financial centers, and their overlapping hours drive trillions of dollars in daily trading volume. During US Daylight Saving Time (March–November) the gap narrows to 4 hours, but the UK also shifts to BST (UTC+1), so the effective difference becomes 5 hours again for part of the overlap and 4 hours during the brief window when only one side has changed.
Best Meeting Times: EST and GMT Overlap
The golden window for US–UK meetings is 9 AM–12 PM Eastern (2 PM–5 PM London). After noon Eastern, London offices are closing. Morning calls before 9 AM Eastern catch London in mid-afternoon.
