Prime Meridian - National Geographic Society

WebThe International Date Line (IDL) is located at about 180° east (or west). It is halfway around the world from the prime meridian (0° longitude), the reference point of time zones, which runs through Greenwich, UK. The date line runs from the North Pole to the South Pole and marks the Western and Eastern Hemisphere divide. WebTrue north is a fixed point on the globe. Magnetic north is quite different. Magnetic north is the direction that a compass needle points to as it aligns with the Earth’s magnetic field. What is interesting is that the magnetic North Pole shifts and changes over time in response to changes in the Earth’s magnetic core. It is not a fixed point.
