The 180th meridian is also called the International Date Line because that is where the day changes from one day to the next. Keep in mind that the date change does not follow exactly the 180th meridian and moves slightly east or west as necessary to accommodate the desires of the various countries that lie along it.
The meridian of 180° east/west longitude crosses parts of the Arctic Ocean,
Russia, Alaska, the Pacific Ocean, Tarawa, Kiribati, Tuvalu, Fiji, Tonga, and
Antarctica.
Much of the International Dateline also coincides with this meridian,
but large parts of it don't.
The meridian at 180 degrees is called the international date line.

180th meridian
This line is known as the antimeridian or simply the 180th meridian. The international date line is sometimes used although it is not entirely correct. The international date line is a "political" convention and sometimes deviates signifigantly from the actual 180 degree longitude
The 180th meridian is on the other side, and the International Date Line generally follows the 180th meridian. (The Prime Meridian is the 0th meridian, with there being 360 lines of longitude across the globe)
The 180th meridian or antimeridian is the meridian which is 180° east or west of the Prime Meridian with which it forms a great circle.
The Prime Meridian is the meridian (line of longitude) at which the longitude is defined to be 0°.The Prime Meridian and its opposite the 180th meridian (at 180° longitude), which the International Date Line generally follows, form a great circle that divides the Earth into the Eastern and Western Hemispheres.
The International Date Line roughly follows the 180th meridian.

The 180th meridian or antimeridian is the meridian which is 180° east or west of the Prime Meridian with which it forms a great circle.
They are separated by imaginary lines called the Prime Meridian and the 180th Meridian (the International Date Line approximately follows this meridian). Since only a small part of Europe is west of the Prime Meridian and even less of Asia is east of the 180th, they are effectively divided by the Atlantic and Pacific Oceans.
