daylight savings?

i get why we have daylight savings but not why some places have it and others dont, can anyone please explain? and name some countries where daylight savings doesnt exist?

Answer 1

Close to the equator, days and nights are of approximately equal length. There is little difference from one month to the next. At the poles, days and nights are of six months' duration each. This means that at midsummer, day length varies from 12 hours at the equator to 24 hours at the pole. The higher the latitude, the longer the day.

As time measurement is human artefact, it makes sense to adjust the clocks to make the most use of the extra length to the days. If the Sun is rising at 4am and setting at 9pm, it makes sense to change the clocks so that the Sun rises at 5am and sets at 10pm. Far more people will use the daylight in the evening than will use it very early in the morning.

Few, if any of the equatorial countries use daylight saving because they don't have the daylight to save but just about all counties away from the tropics take advantage of the longer day by having longer evenings.

Please tell me this is a joke, and you're not really that ignorant! Daylight savings time is just a convenience to commerce. It is a measurement, a counting system, not having the slightest effect on the actual global temperature. Oh wait, let me think about this. Maybe it does. As you know, once the sun goes down, the air and the surface of the ground start to cool off. So when the evening rush hour happens after sunset, presumably it provides less extra heat, because it is being cooled by the cooler air. Maybe if instead of daylight savings time, we had darkness savings time . . . but then the morning rush hour is also moved ahead . . . your question is giving me a headache.

I am not sure of countries, but I do know that the states of Arizona and Hawaii do not observe daylight savings time. The reason that they don't is because they are already two of the sunniest states in the nation. Changing to daylight savings time does not impact them the way that it might in states that don't have as much annual sunlight.
