Yes it is.
The International Date Line is an imaginary line that roughly follows the 180-degree meridian. It is not a "palline" but rather a geographic marker used to indicate where one calendar day ends and another begins.
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 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.

No, the International Date Line is not used to measure latitude. It marks the boundary between one calendar day and the next, mostly following the 180° line of longitude. Latitude is measured north or south from the equator.
The 180 degrees longitude line, also known as the International Date Line, is a navigational line used to mark the change of one calendar day to the next. It is not physically drawn on maps or globes, but rather serves as a demarcation for time differences between different regions of the world.
India is still a developing nation and the people are happy and used to it now.
Although the line at 180° passes right through Fiji, the International Date Line at that latitude is relocated to the east sides of Western Samoa and Tonga. I don't know how many miles that is, but it's at least 6° of longitude east of 180°. (Western Samoa relocated the International Date Line to its east side in December, 2011, less than seven months before the time of this writing.)
Yes, there are maps that show the International Date Line which runs roughly along the 180° line of longitude, deviating to accommodate territories or to avoid dividing countries. It's a conceptual line rather than a physical one, used to define where one day ends and the next begins on Earth.
No. The "Prime Meridian" (Greenwich Meridian) is 0° longitude and runs through Greenwich, England, western Europe, and Africa. The International Date Line is on the other side of the world, at 180° longitude (east or west is the same line), and marks the start of each new calendar day. It is midnight at the Date line when it is noon at the Prime Meridian. The actual line has detours to accommodate Russia, the Aleutians, and New Zealand. The two meridians form a circle around the planet, and each divides the Eastern Hemisphere from the Western Hemisphere.
The International Date Line is an imaginary line on the Earth's surface that determines the change in calendar date when crossed. It roughly follows the 180° meridian and is used to mark the transition between consecutive calendar days. Crossing the date line from east to west results in gaining a day, while crossing from west to east results in losing a day.
None. The Pacific island nation of Kiribati used to be split by the IDL, but that was corrected in 1996. Since then, the line crosses no single political entity ... city, county, state, country, etc.
