In which ocean is the international date line located?

• A. Atlantic Ocean
• B. Pacific Ocean
• C. Indian Ocean
• D. Arctic Ocean

Answer: (B)

The International Date Line runs mainly through the Pacific Ocean along roughly the 180th meridian, with small detours to pass around islands and territories. This line marks where the calendar day changes, so crossing it from west to east subtracts a day and crossing from east to west adds a day. Because its path sits largely in the Pacific, that ocean is where the line is located for most of its length; the Atlantic, Indian, and Arctic oceans do not contain the line.
