Planning across the country
When you fix a call or a broadcast for people in several parts of Antarctica, give the time with its zone, or use the converter to show every zone at once.
Where most people are
Measured by the people living in towns of 15,000 or more (GeoNames figures), the busiest clock in Antarctica is the one kept in Casey, UTC+8 in January: about 0 people, or 0% of the total across all the zone areas. The other clocks, Davis (UTC+7), DumontDUrville (UTC+10), Mawson (UTC+5), McMurdo (UTC+13), Palmer (UTC−3), Syowa (UTC+3), Troll (UTC), cover only places with no town that large.
A worked example
When it is 9:00 am in Casey in January, it is 10:00 pm in Palmer (previous day), 1:00 am in Troll, 4:00 am in Syowa, 6:00 am in Mawson, 8:00 am in Davis, 11:00 am in DumontDUrville, 2:00 pm in McMurdo.
A worked example for July
When it is 9:00 am in Casey in July, it is 10:00 pm in Palmer (previous day), 3:00 am in Troll, 4:00 am in Syowa, 6:00 am in Mawson, 8:00 am in Davis, 11:00 am in DumontDUrville, 1:00 pm in McMurdo.
The widest gap inside the country
The two clocks that are farthest apart differ by 16 hours in January and by 15 hours in July, because not every part moves its clocks.
Antarctica and the rest of the world
When it is 12:00 noon in Casey, it is 9:30 am in India; 4:00 am in London in January and 5:00 am in July; 11:00 pm the previous day in New York in January and 12:00 am in July. Other parts of Antarctica are earlier or later than that by the amounts in the table at the top of this page.
