Daylight Savings Time (DST)

Time during which clocks are set one hour or more ahead of standard time to provide more daylight at the end of the working day during late spring, summer, and early fall.  Daylight Savings Time in other countries varies from that of the USA.  Most countries near the equator do not deviate from Standard Time.  (Also called Summer Time, Daylight Time or Advanced Time)

Check local dates and times for Daylight Savings Time.

Daylight Savings Time is a political issue, not a scientific one and decisions regarding its observance are make in a political context.  Consequently, there is no uniformity throughout the world on when Daylight Savings Time will be observed or how much the clock will be retarded or advance.  There is no international organization officially charged with maintaining records of dates of changeover between Standard and Daylight Savings Time for the countries of the world.

The changeover between Standard and Daylight Savings Time has been given only to the nearest day, since that is the best level of information available for many countries.  For a few countries there are no set dates when clocks are switched between Standard and Daylight Savings Time; the decision when to switch is made each year.

Users are cautioned to use discretion when using the Daylight Savings Time information of a country when that location is changing between Standard and Daylight Savings Time.  Also, be especially cautious about time when dealing with a country that does not have precisely defined dates for the change between Standard and Daylight Savings Time.
