Zero degrees longitude, sometimes called the Greenwich Meridian after the observatory in Greenwich England where the system of latitude and longitude was worked out. The happy accident is that the 180 degree meridian, the International Date Line, is situated in the ocean where it causes relatively little trouble for major land masses.
