The International Date Line corresponds closely, but not exactly, to the 180 degree line of longitude.
lines of longitude are lines drawn north and south and measure east and west a famous line of longitude is the Prime meridian
The Prime Meridian is a line of longitude, and it sits at 0 degrees longitude.
The straight line between the poles is the Earth's axis of rotation. The curved lines between the poles and along the surface are the meridians of longitude.
The major line of longitude located at 180 degrees longitude is the International Date Line.
180 degrees longitude is the meridian that should be the International Date Line. But in actuality, the date line was drawn with several zigs and zags in it, in order to avoid cutting across land, which would have placed different parts of the same country in different calendar dates. So the Date line deviates from the 180 meridian in several places.

North Dakota occupies the range of longitudes between roughly 96.56° and 104.04° West. Any 'line' drawn at any longitude within that range crosses territory in North Dakota.
For the same reason that your lawn is not above or below ground,or something like that.Zero and 180 degrees longitude form the boundary between east and west,so they are both, and they are neither.
The frontier was irregular and, like nearly all frontiers in Europe, was not drawn along a line of longditude.

longitude
Lines of Longitude are imaginary lines that run from the North Pole to the South Pole. The main line of longitude, the Prime Meridian (zero longitude), passes through the Greenwich Observatory, London, England.
The major line of longitude located at 180 degrees longitude is the International Date Line.
An angle with 180 degrees is a straight line, so it's known as a straight angle.
The lines of longitude are vertical; longitude measures the horizontal distance from 0 degrees longitude. Here is a mnemonic that helps me: Latitude sounds a little like 'ladder-tude', and the rungs of a ladder are horizontal. I picture myself 'stepping up or down' the lines of ladder-tude, and this moves me farther north or farther south. That leaves vertical for longitude. While the lines of longitude are drawn from north to south, their locations measure a parameter that changes from east to west; longitude tells you how far east or west you are (in degrees, not distance) from the prime meridian (zero degrees longitude). Lines of latitude are drawn from east to west, and they measure how far north or south you are. So running the risk of confusing you, the "concept" of longitude (what is your position east/west of the prime meridian) is really horizontal in nature. This can be a little hard to grasp. Draw a line on a piece of paper; make the line exactly one inch from the left margin. You have drawn the line 'up and down', but the line is there to tell you how to get one inch from the margin (left-right) no matter where you are on the paper. And no matter where you are on the line, you are one inch to the right of the left margin. So if you travel up and down a line of longitude, you might cover several thousand miles, but you haven't budged from your measure of longitude-- how far you are (in degrees) from the prime meridian. As you travel along your line of longitude, you see hash-marks with changing numbers of degrees. These are not changes in longitude, but in latitude. They answer: How far north or south am I, along this line of longitude? When doing navigation, the simple thing is that lines of longitude are all long. Since they all go through both the North and South Pole, they are all the same length. Latitude lines vary in length. Latitude: LAT=FLAT Longitude: LONG (heights)
The International Date Line runs roughly along the 180° longitude, (opposite the Prime Meridian), but it is drawn with diversions to pass around some territories and islands.
