England lies at the centre of the prime meridian (0 degrees longitude), which was established in Greenwich, England. This placement led to Greenwich Mean Time (GMT) being adopted as the world's time standard at the International Meridian Conference of 1884. Since GMT was based on the time at which the sun is at its highest point over the prime meridian, it became the starting point for the world's different time zones. This historical decision is why England is in the 0 time zone, playing a crucial role in global timekeeping.
