London Time Overview

London operates on Greenwich Mean Time (GMT) during winter and British Summer Time (BST) during daylight saving months. It is one of the most important global time reference points for finance, travel, and international coordination.

Because London sits between North American and Asian markets, its working hours overlap with major global financial centers. This makes it a key timezone for international business communication and trading activity.
