1. Understanding London Time: A Quick Overview
London operates on Greenwich Mean Time (GMT) during standard time and British Summer Time (BST) during daylight saving time. London time is important for scheduling international calls, planning travel, and understanding global events.
1.1 What is Greenwich Mean Time (GMT)?
Greenwich Mean Time (GMT) is the standard time against which the world’s time zones are measured. GMT refers to the time at the Royal Observatory in Greenwich, London. It is often used as a reference point for coordinating activities across different time zones.
1.1.1 Why is Greenwich Important for Time?
Greenwich is important for time because the Prime Meridian, which marks 0 degrees longitude, passes through the Royal Observatory. In 1884, an international conference designated the Greenwich Meridian as the prime meridian of the world, making Greenwich the center of world time.
1.2 What is British Summer Time (BST)?
British Summer Time (BST), also known as daylight saving time, is observed in the United Kingdom from late March to late October. During BST, clocks are advanced by one hour, providing an extra hour of daylight during the evening. This shift aims to save energy and promote outdoor activities.
1.2.1 When Does BST Start and End?
BST starts on the last Sunday of March and ends on the last Sunday of October. On the starting date, clocks are advanced by one hour at 1:00 AM GMT. On the ending date, clocks are turned back one hour at 2:00 AM BST.
