Q: International Date line passes through____.
  • A. 0⁰ Greenwich
  • B. 180⁰ Greenwich
  • C. 90⁰ Greenwich
  • D. 270⁰ Greenwich
Correct Answer: Option B - In the year of 1884, an international conference was organized at the Washington D.C. (United States of America) in which time zone of 1 hour was set up at 15º longitude. On the same time the International Date Line was also adopted which passes through the 180º meridian and it separates the whole world into two consecutive calendar days. It is not a perfectly straight line. It passes through the middle of Pacific ocean roughly following the 180º line of longitude. There is a difference of one day on either side of the 180º meridian. The time increases east of the prime meridian and decreases to its west. The maximum number of time zone is found in France as 12 time zone.
