Time in Antarctica now

Antarctica has several official time zones. The most used is CAST (UTC+08:00). The country currently uses times ranging from UTC-3:00 to UTC+13:00, depending on the region.

Part of the territory observes daylight saving time (DST), which moves the clock forward one hour during part of the year.

Antarctica has a territory that spans several time zones; the country therefore uses multiple time zones.
