The IDL should nominally follow the meridian of longitude that is 180 degrees from the Greenwich
Prime Meridian ... roughly down the middle of the Pacific Ocean. But in defining the line, it was
zigged and zagged where necessary to avoid cutting across nations and politically contiguous
island groups.
180 degrees
Midnight, on the morning of the day after.
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
No, the international date line is a line of longitude, not latitude.
the great circle is formed by the prime meridian and the international date line
The International Dateline approximately follows the meridian of 180° longitude.
The International Dateline approximately follows the meridian of 180° longitude.

The International Dateline roughly follows the line of longitude that is both 180° E longitude and 180° W longitude, which passes through the western Pacific Ocean. The Dateline is shifted east or west in several locations to maintain a common date for associated countries or regions (Russia, US, New Zealand).
No. It would be the western boundary.East longitude is measured starting from the Prime Meridian and increasing eastward.It reaches the maximum of 180° east in the vicinity of the International Date Line.
The International Date Line passes through the Pacific Ocean. It is an imaginary line that runs from the North Pole to the South Pole, mostly along the 180° longitude line.
The International Date Line (IDL) is roughly along 180° longitude, with diversions to pass around some territories and island groups.
Any merididian of longitude is an imanginary line between the north pole and the south pole. There is one for every possible longitude, and the International Dateline roughly but not exactly follows the one marked 180°, through the Pacific Ocean.
international dateline
You're getting at the International Dateline. It roughly follows the line of longitude at 180 degrees east/west, and really has little to do with standardized international dates, whatever those are.
The International Date Line is an imaginary line of longitude of 180 degrees around the Earth. It works when a person crosses the line from the east to the west a day is added. The opposite effect happens when crossing from west to the east with a day subtracted.
The Greenwhich meridian also Prime Meridian is 0 degrees longitude and International Date Line roughly follows the 180° longitude or antimeridian. The antimeridian is the meridian which is 180° east or west of the Prime Meridian.
