The international date line is measured approximately from the 180 degree median longitude line. This is an arbitrary line that determines when a date change takes place within the day.
180 degree longitude
... the meridian of 180° longitude.
The Equator is the imaginary line that runs east and west half way between the north and south poles. The equator has a latitude of 0 degrees which divides the Earth into the Northern Hemisphere and Southern Hemisphere. The Equator is one of the five named circles of latitude on Earth. Going from North to South, the circles of latitude are called the Arctic Circle, Tropic of Cancer, Equator, Tropic of Capricorn, and the Antarctic Circle.
prime meridian International Date Line
No, the international date line is a line of longitude, not latitude.
Roughly 180o, the date line wiggles to avoid passing over inhabited land so that people don't have the complication of living with the dateline passing through their town.

That would be the "International Date Line" which is skillfully drawn to avoid crossing any land mass.
It is roughly, but the actual date line deveates around some islands and territories.
No. It crosses all of the parallels, and generally follows the 180° meridian.
