Rothera, Antarctica · UTC-3
Convert time from Rothera
Rothera is in the Antarctica/Palmer timezone (CLT/UTC-3), with no daylight saving time observed. Rothera Research Station sits on Adelaide Island, on the Antarctic Peninsula, at 67 degrees south. It is the British Antarctic Survey’s main base: a hub for geology, glaciology, marine biology, and atmospheric research. About 150 people work there in summer, fewer in the polar winter.
Antarctica has no civil timezone. Research stations adopt practical times based on their supply lines and partnerships. Rothera runs on Antarctica/Palmer in the IANA database, which corresponds to Chile Time, UTC-3, year-round. This makes sense: Rothera is supplied and staffed largely through Punta Arenas in Chile, and keeping the same time as the supply chain simplifies logistics.
At 67 degrees south, the solar extremes are significant. In December, the sun never sets: 24 hours of daylight. In June, the sun barely rises, if at all. The research station runs on a schedule that ignores the sky entirely for much of the year: meal times, work shifts, and recreation schedules operate on clock time regardless of what the Antarctic summer or winter is doing outside.
