There are two islands known as the Diomedes, about two and a half miles apart in the middle of the Bering Strait, between Siberia, Russia and Alaska. One of them, Little Diomede, belongs to the US, and has a population of about 150. The other island, Big Diomede belongs to Russia and is uninhabited, except for Russian border guards.
The space between these two islands marks not only an
international border, but the International Date Line as well,
making it possible for the folks on Little Diomede to wake up on a
Sunday and look across the water to Big Diomede, where it’s
already Monday. I guess this means the Russians are ahead of
the US, at least by a day.
