In theory, ships are supposed to adopt the standard time of a country if they are within its territorial waters within 12 nautical miles (14 mi; 22 km) of land, then revert to international time zones (15° wide pole-to-pole gores) as soon as they leave. In practice, ships use these time zones only for radio communication and similar purposes.
Relationship of Earth's axial tilt (ε) to the tropical and polar circles. The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the centre of the Sun can remain continuously above or below the horizon for twenty-four hours; as a result, at least once each year at any location within the Arctic Circle the centre of the Sun is visible at local midnight, and at least ...

Countries and territories that are intersected by the equator (red) or the Prime Meridian (blue), which intersect at "Null Island". The equator during the boreal winter, spanning from December to March. The equator is the circle of latitude that divides Earth into the Northern and Southern hemispheres.
The antimeridian passes mostly through the open waters of the Pacific Ocean but also runs across land in Russia, Fiji, and Antarctica. An important function of this meridian is its use as the basis for the International Date Line , which snakes around national borders to maintain date consistency within the territories of Russia, the United ...
On Victoria Island, Canada, part of the border between Northwest Territories (green) and Nunavut (white) is defined by the 70th parallel north. The 70th parallel north is a circle of latitude that is 70 degrees north of the Earth's equatorial plane, in the Arctic.
The Alaska Time Zone observes standard time by subtracting nine hours from Coordinated Universal Time (UTC−09:00). During daylight saving time its time offset is eight hours ( UTC−08:00 ). The clock time in this zone is based on mean solar time at the 135th meridian west of the Greenwich Observatory .
The 69th parallel north is a circle of latitude that is 69 degrees north of the Earth's equatorial plane, in the Arctic.It crosses the Atlantic Ocean, Europe, Asia and North America, and passes through some of the southern seas of the Arctic Ocean.
