It’s come up quickly and this Sunday, March 13 at 2 a.m. is the time to turn your clocks one hour ahead for daylight time.
For some people, there is no daylight time or time zone, like researchers living and working in Antarctica.
Antarctica’s 24 hours of sunlight in summer and 24 hours of darkness in winter make daylight and standard times unnecessary.
And it falls under all the time zones because the longitude lines used to define time zones all meet at the poles, so the continent could use any of the world’s time zones.
To make things convenient for researchers and visitors, each research base determines which time zone to adopt.
Some research stations follow the time zone of their home country but others, like the McMurdo station and Palmer station, both run by the US, synchronize their time to the closest point in the inhabited world.
McMurdo follows the same time as Christchurch, New Zealand, since most visitors and researchers to the station use that city to go to Antarctica.
This year, McMurdo will change to daylight time when Christchurch does.
Palmer Station, on the other hand, follows Chilean time and will not turn to daylight time starting this year as Chile has stopped using it.
