South of Kiribati, the IDL returns westwards but remains east of 180°, passing between Samoa and American Samoa.
In much of this area, the IDL follows the 165°W meridian.
Conventionally, the IDL is not drawn into Antarctica on most maps.
(See § Cartographic practice and convention below.) A person who goes around the world from east to west (the same direction as Magellan's voyage) would gain or set their clock back one hour for every 15° of longitude crossed, and would gain 24 hours for one circuit of the globe from east to west if they did not compensate by setting their clock forward one day when they crossed the IDL.

In contrast, a west-to-east circumnavigation of the globe loses an hour for every 15° of longitude crossed but gains back a day when crossing the IDL.
The IDL must therefore be observed in conjunction with the Earth's time zones: on crossing it in either direction, the calendar date is adjusted by one day.
Kiribati's easternmost islands, the southern Line Islands south of Hawaii, have the most advanced time on Earth, UTC 14 hours.

Weakened by disputes, it was dissolved in 1876, but it was succeeded by three later Internationals, which sought to spread communism throughout the world.
For the two hours between and UTC each day, three different calendar dates are observed at the same time in different places on Earth.
For example, at UTC Thursday, it is Wednesday in American Samoa (UTC−11), Thursday in most of the world, and Friday in Kiritimati (UTC 14).
