180 of them.
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.
There are two. They are the Greenwich Meridian and 180 degrees longitude, the originally defined International Date Line.
The line of longitude for a place that is halfway between the prime meridian and the 80th line of longitude and west of the prime meridian would be -40 degrees longitude. The prime meridian is at 0 degrees, and halfway between 0 and 80 is 40 degrees. Since the location is west of the prime meridian, the longitude would be measured as negative.
The line of longitude where one day ends and another begins is called the International Date Line. It roughly follows the 180° meridian in the Pacific Ocean and marks the transition between calendar days.
A meridian of longitude is an imaginary line made up of all the points on earth that have the same longitude, whatever that number is. If you draw any meridian of longitude on a globe, it looks like a solid half-circle between the north and south poles.

24 Hours. When you pass the international date line which is the meridian of 180 longitude, you add a day if going west or subtract a day going east.
The line of longitude for a place that is halfway between the prime meridian and the 80th line of longitude and west of the prime meridian would be -40 degrees longitude. The prime meridian is at 0 degrees, and halfway between 0 and 80 is 40 degrees. Since the location is west of the prime meridian, the longitude would be measured as negative.
If you take a globe or a map and draw a line through all the points that haveexactly the same longitude, the line you get is the meridian of that longitude.
