The ideal, technical requirement for an International Dateline would place it
exactly on the meridian of 180° longitude, all the way between the north and
south poles. But there are several places where that would have split a single
village, town, city, state, island, or group of islands into two different calendar
dates. (One of them would have been the state of Alaska, and therefor the USA.)
In order to avoid doing that, the Dateline was zigged and zagged in a number of
places, and substantial parts of it lie along different longitudes.
No, the international date line is a line of longitude, not latitude.

Whether travelling to the West or to the East from the Prime Meridian (zero Longitude) the International Date Line is 180 degrees Longitude.
International Date Line
No. Greenwich Mean Time is the timezone located along the Prime Meridian, 0º longitude. The International Date Line is on the exact opposite side of the earth at 180º, with some variance. The International Date Line is 12 hours away from Greenwich Mean Time in many areas.
The International Date Line is located at approximately 180 degrees longitude. Las Vegas is situated at about 115 degrees west longitude. Therefore, the International Date Line is roughly 65 degrees of longitude away from Las Vegas.
International Date Line
The major line of longitude located at 180 degrees longitude is the International Date Line.
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.

The international date line
The line at 180 degrees longitude is called the International Date Line. It serves as the boundary where each calendar day begins, and crossing it leads to a change in date. The line runs from the North Pole to the South Pole and roughly follows the 180th meridian.
