Time in Antarctica

Antarctica sits on every line of longitude because the South Pole is on the continent.

[1] In most areas south of 80 degrees latitude, Coordinated Universal Time is assumed despite the limited presence of clocks.

The majority (95 percent) of the continent is located south of the Antarctic Circle, and the midnight sun phenomenon renders the observation of DST unnecessary.

However, a few regions such as the Ross Dependency and, formerly, Palmer Land, observe the time and use of DST of the countries they are supplied from, New Zealand and Chile, respectively.

[1] The areas have DST during the southern summer, when there is the northern winter, including January.
