What Time Is It In Antarctica?

TL;DR

Antarctica has no official time zone because all meridians converge there, so each research base simply uses the time zone of its supply country.

Key Points

• 1.Antarctica is the only continent on Earth with no official time zone. All longitude lines converge at the South Pole, meaning you could technically run through every time zone in seconds.
• 2.Research bases each pick their own local time based on their supply country. With only ~5,000 people maximum and no permanent residents, there's no authority to mandate a single standard time.
• 3.The sun rises and sets only once per year in Antarctica. This permanent daylight or darkness makes conventional timekeeping even less meaningful for those stationed there.
