Nestled in the Bering Strait between Alaska, United States, and Chukotka, Russia, lie two remote islands that not only mark the divide between two nations but also straddle the enigmatic International Date Line.
The Diomede Islands, consisting of Big Diomede (Tomorrow island) and Little Diomede (Yesterday island), serve as a geographical testament to the complexities and fascinating implications of time and international boundaries. To the north is the Chukchi Sea and to the south is the Bering Sea.
Big Diomede belongs to Russia but Little Diomede belongs to the U.S.A. The Islands are located approximately 3.8 km or 2.4 miles apart at their closest point making it the shortest distance between these two big nations.
The International Date Line, an imaginary line running roughly along the 180° meridian, determines the transition between calendar dates. As one crosses the line from the west to east, they essentially "gain" a day while crossing from east to west results in "losing" a day. This transition is significant, as it affects not only the date but also the time, potentially creating a 24-hour difference.
The proximity of the Diomede Islands to the International Date Line has intriguing implications. Due to the time difference between Russia and the United States, Big Diomede lies in "tomorrow", while Little Diomede is in "today" or "yesterday" depending on the reference point.
