Areas that have never used DST

During DST clocks are normally set forward one hour from standard time during the summer months and back again in the fall to make better use of natural daylight.

DST per Continent

Less than 40% of the countries in the world use DST today. Since daylength variations are negligible around the equator, most tropical territories do not change their clocks.
