The International Date Line: A Path of Time and Confusion

TLDRThe International Date Line is an imaginary line that divides the world into two separate hemispheres, causing time zone chaos and confusion. It determines when days begin and end and affects travel across the line. However, its zigzag shape and arbitrary location have led to anomalies and shifting actions by countries. The line runs through the Pacific Ocean, causing islands and regions to have different days despite their proximity. The establishment of a standardized system for timekeeping was crucial for global trade and commerce, but the International Date Line remains a source of complexity.
