In the Bering Strait, there are a pair of small islands ... "Big Diomede" and "Little Diomede".
Big Diomede belongs to Russia. Little Diomede belongs to the USA (Alaska).
The solid land parts of their coasts come within about 2.4 miles of each other, and they're often
joined by a solid ice bridge for much of the year.
The International Dateline runs between the islands.
So you have two places that are about 2.4 miles apart. People could stand there and flash
mirrors at each other on a clear day, or flashlights on a clear night, and maybe even drive
snowmobiles across the ice during the winter. One of the places is in Russia, the other one
is in the USA, and it's never the same date, time, or day of the week at both places.
This would be the country closest to the east of the International Date Line, which is Kiribati.
Alaska is.
It is Alaska.

Alaska, USA is just east of the International Date Line.
The closest continent east of the International Date Line is North America.
New Zealand is officially the first country to celebrate any day as it is closest to the International Date Line.
Alaska and Hawaii. If you go to the mainland, then California, Oregon, and Washington are the closest.

The volcano that straddles the 180 degree meridian is on Taveuni, which is the third largest of the Fiji islands. The International Date Line deviates eastward from the island.One of the closest volcanoes to the International date line is a twin submarine volcano called Volcano W in the Kermadec Islands. It is located at latitude: 31.85°S and longitude: 179.18° in the SW Pacific.
No countries cross the International Date Line. The line was intentionally drawn that way to spare any country the nightmare of always having two different calendar dates within its borders.
