Which country's territory lies in all four hemispheres — north and south of the equator, and on both sides of the 180th meridian?

Explication

Kiribati's 33 islands — 32 low-lying atolls and the raised island of Banaba — are scattered over more than three million square kilometres of the Pacific, straddling both the equator and the 180th meridian. Because the date line originally ran straight through the middle of the country, half of it lived a day behind the other half until 1995, when Kiribati bent the line eastwards so everyone could share one calendar date.
