The idea of moving the Prime Meridian (0^\circ) to the International Date Line (IDL) (roughly 180^\circ) involves shifting the global reference point for both longitude and time.

Here are some reasons for such a monumental change:

🌍 Arguments FOR Moving the Prime Meridian to the IDL

The arguments generally focus on a more logical or symmetrical geographical and temporal system.

Symmetry and Simplicity:

By making the 180^\circ meridian the zero point, the entire globe could be labeled with longitude values ranging from 0^\circ to +180^\circ (East) and 0^\circ to -180^\circ (West), which technically still results in the same 360^\circ system but could be seen as having a clear geographical center point in the Pacific.

Geographical Neutrality:

The current Prime Meridian at Greenwich was chosen primarily due to the dominance of the British Empire's maritime and cartographic influence in 1884. Moving the zero point to the IDL, which passes almost entirely over the open ocean (the Pacific), would make the global time and coordinate system geographically neutral and less centered on a single nation's history.

Logical Center of the Earth:

The IDL lies where the calendar day naturally begins and ends. Using this line as the zero point might be argued as more logical because the Prime Meridian would then become the line where the day is halfway over (12 hours of difference), creating a symmetrical temporal division.
