Meridian Coordinates [LEGIT]

Meridian coordinates aren't just for location; they are the foundation of our global time system. Because the Earth rotates 360° every 24 hours, it moves approximately .

To find a specific coordinate, you measure the angle between the Prime Meridian and your location, with the center of the Earth as the vertex. meridian coordinates

This is why time zones are generally spaced 15 degrees apart. When you cross a meridian line roughly every 15°, you move into a different hour of the day. This connection is why "meridian" is also a temporal term— Ante Meridiem (A.M.) means "before the meridian" (noon), and Post Meridiem (P.M.) means "after the meridian." Practical Applications Today Meridian coordinates aren't just for location; they are

Every coordinate system needs a "zero" point. For latitude, the starting point is the Equator. For meridian coordinates, the world agreed upon the during the International Meridian Conference in 1884. This is why time zones are generally spaced 15 degrees apart

Every smartphone uses a receiver to calculate its position based on the intersection of latitude and meridian lines.
