Best time to meet between GMT & UTC
Working hours are 9am–6pm in each city. The bright band is where they overlap — when both sides are at their desks.
Daylight saving shifts this gap by up to 1 hour
The difference between GMT and UTC swings between 1 and 0 hours across the year as each side starts or ends daylight saving. Regions on GMT switch to BST (UTC+1) during daylight saving time. This page always shows the live, DST-aware difference.
