The Birthplace of Global Timekeeping

The Time in London carries historical and global significance. Greenwich, a district in southeast London, is the origin of the Prime Meridian (0° longitude), which is the reference point for all time zones around the world. That’s why we have terms like “GMT” and “UTC”—they’re all based on the Time in London.

This system, established in the 19th century, turned London into the heart of the world’s timekeeping network. The Royal Observatory in Greenwich remains a must-visit destination for anyone interested in astronomy, navigation, or simply standing on the famous line that divides the eastern and western hemispheres.

Daylight Saving Time in London: When the Clocks Change

Every year, the Time in London changes twice due to daylight saving:

1. Spring Forward: On the last Sunday in March, clocks move forward by one hour (from GMT to BST).
   
   

2. Fall Back: On the last Sunday in October, clocks move back by one hour (from BST to GMT).
   
   

This means that during summer months, the sun sets later, often after 9:00 PM, allowing longer evenings perfect for enjoying London’s parks, riversides, and festivals. In winter, the days become shorter, with sunsets as early as 4:00 PM.

If you’re traveling or conducting business in London, it’s important to keep track of these clock changes to stay aligned with appointments, flights, or virtual meetings.
