What countries does the international dateline pass through?
At 180 degrees longitude (for the most part), directly opposite the Prime Meridian (which passes through Greenwich, England), the International Dateline extends through the middle of the Pacific Ocean and a large portion of the Arctic Ocean. It would pass through the tip of eastern Russia and across Alaska’s Aleutian Islands, but by agreement the line jogs around both. Similarly, the line takes an angled path in the southern hemisphere to avoid bisecting any countries.
