The 180th meridian or antimeridian is used as the basis for the International Date Line because it for the most part passes through the open waters of the Pacific Ocean separating the east and west hemispheres.
The imaginary line 180 degrees east and west of the Prime Meridian is called the International Date Line. Crossed from west to east, the date moves back by one day.
At the Greenwich meridian, and the international date line.
The International Date Line follows the 180th meridian to prevent dividing countries into two different calendar days. It bends around certain territories and islands to ensure that each country remains within a single day. This results in the International Date Line not being a straight line.
East and west meet at the International Date Line in the Pacific Ocean, which is located at roughly 180 degrees longitude. This line serves as the boundary between one day and the next, and marks the transition between the eastern and western hemispheres.
The International Date Line deviates from the 180 degrees meridian to accommodate various national and political boundaries. This helps to avoid causing confusion with neighboring countries that prefer a specific time zone. Additionally, it also aligns with certain cultural and economic considerations in different regions.
It's a meridian, directly opposite the Prime Meridian.
The International Date Line.
The opposite of the International Date Line is the Prime Meridian, which is located at 0 degrees longitude and passes through Greenwich, England. While the International Date Line determines where one day ends and another begins, the Prime Meridian serves as the starting point for measuring longitude and time zones.
The Prime Meridian. Opposite Prime Meridian (180-degrees Longitude) is The International Date Lin.
The Prime Meridian and its opposite the 180th meridian (at 180° longitude), which the International Date Line.
The International Date Line is the imaginary line opposite the Prime Meridian that does not currently run through any nation. It is located opposite the Prime Meridian at 180 degrees longitude and serves as the transition line for changing calendar days.
The International Date Line combined with the Prime Meridian makes a complete circle around the Earth. The Prime Meridian is at 0 degrees longitude, and the International Date Line is opposite it at 180 degrees longitude.
The meridian exactly halfway around the world from the prime meridian is called the 180th meridian or the antimeridian. This line represents the opposite side of the Earth from the prime meridian and is where the International Date Line is located.
The Midnight Meridian refers to the line of longitude directly opposite the Prime Meridian, marking the halfway point between the International Date Line and the Prime Meridian. It is where each calendar day begins.
The Prime Meridian is an imaginary line that divides the Earth into Eastern and Western Hemispheres, but the day officially changes at the International Date Line, which is located approximately opposite the Prime Meridian. The International Date Line is where the calendar day officially changes.
If you travel to any place that is half-a-globe around the earth from the Prime Meridian, you'll be located at longitude 180 degrees. If you're expecting to find a line there, you'll be disappointed. There is no line there.
It varies, because the International Dateline doesn't follow a single meridian.There are several zigs and zags in it. But in the spirit of your question, theDateline is nominally directly opposite the Prime Meridian, at 180° longitude.
