Namibia does not observe Daylight Saving Time in 2018 and has not put its clocks back one hour at the beginning of April.
Since Namibia is south of the Equator its standard (or winter) time used to be from April to September. The last clock change took place in 2017.
Until 2017, Namibia Winter or Standard Time (one hour in advance of Greenwich Mean Time) applied from the first Sunday of April through May, June, July, and August to the first Sunday in September.
The international dialling code for Namibia is 264.
