The concept of time zones and the international date line is a human agreement rather than an empirical scientific fact. The international date line, running through the Pacific Ocean, marks the boundary where days change. The location of this line has been historically ambiguous and subject to the whims of governments. While a resolution in 1884 established the prime meridian at Greenwich, the exact position of the international date line remains unsettled. Some countries have unilaterally moved the line for political or commercial reasons. This fluidity challenges map makers and leads to discrepancies in depicting the date line. For instance, the location of the date line around the Cook Islands is still unclear, and different sources provide conflicting information.
