Since Antarctica is largely uninhabited, the continent is not officially divided up into time zones. However, there are a number of research stations, each of which observes its own local time. Some stations use the time zone of the country that operates or supplies them; others observe the local time of countries nearby.
For some of the stations, the exact time and date of the DST change is sometimes not easy to predict as it depends on when supplies and personnel arrive for the summer season.
Check our Time Zone News to receive up-to-date information about DST and time zone switches.
If you have information about a DST switch that is listed as a preliminary date, please let us know.
