Does sunset time change on the equator?

Does sunset time change on the equator?

Regardless of the season, the sun rises and sets perpendicularly from the horizon at the equator. This effect causes the dawn to appear three minutes sooner and the sunset to appear three minutes later. The sun appears to move across the sky at exactly the same rate it does for points farther away from the equator.

During the summer months in Hawaii, the sun is visible all day long because there are no clouds in the sky. In the wintertime, when it's cloudy, people have to be brought in for their shift starts and ends. The sun rises and sets at almost exactly the same time every day, which means that if it was sunny out one minute ago, then it must be dark now. The only thing that changes is the color of the sun as it drops below the horizon.

At the North Pole, sunset is in the middle of the night and sunrise is early in the morning. There are no sunsets or sunrises at the North Pole because there is no sun to set or rise. At the South Pole, sunset is early in the afternoon and sunrise is late in the morning. There are no sunsets or sunrises at the South Pole because there is no sun to set or rise. Between the poles is the Arctic Ocean, its southern border being defined as a line drawn straight from the North Pole to the South Pole.

Where does the sun rise and set at the equator?

Because the sun is constantly high in the sky at the equator, the time it takes to rise and set doesn't change all that much. The sun is either just above or just below the horizon at the poles, depending on whether it is summer or winter. It takes a little longer in the polar regions than it does at the equator.

The earth's axial rotation causes the daily cycle of light and darkness. At the equator, the sun rises due east and sets west. At the north pole, the sun never moves from south to north; instead it stays up all night and returns the next day to the same position it started from. At the south pole, the sun never moves from north to south; instead it stays down all night and returns the next day to start again from zero degrees south.

At the equator, the sun appears to rise and set exactly at noon every day. But because the axis of the earth spins around once in 24 hours, at any given place on the surface of the earth there are two points on the horizon which are rising and two which are setting at any given moment of time.

Thus at the equator the length of daytime varies by only 10 percent from one year to another. But at the poles the length of daylight varies by almost 400 percent between the seasons.

Why does the sun set later in the southern hemisphere?

As the Earth rotates in orbit, the entire southern hemisphere comes into contact with sunlight later and departs it sooner. Because of the tilt of the Earth's axis, dawn is later and sunset is earlier in the southern hemisphere in June. The difference is about 12 hours.

The effect is called "seasonal lag" and it's why we don't see direct sunlight at the same time every day in Melbourne: sometimes there's darkness before sunrise and after sunset, even though it's not night.

Melbourne experiences this seasonal lag best between October and March when we get an extra day with morning sunshine and an extra night with moonlight. The city doesn't experience true winter because of its proximity to the equator, but the days are shorter and the weather is cooler.

During these months the sun rises around 3am and sets around 9pm, which means that for two hours each day you can look up at the sky and see the bright blue color of daylight.

This isn't always possible due to the location of cities across the world, but it is common in Australia's capital city.

In the southern hemisphere summer the sun rises around 7am and sets around 4pm, which means that there are only nine hours of daylight each day.
