Back when this calculator was first created, we decided to use a non-standard definition of longitude and time zone, to make coordinate entry less awkward. So on this page, both longitude and time zone are defined as positive to the west, instead of the international standard of positive to the east of the Prime Meridian. We maintain this page as a courtesy to those people who, for whatever reason, prefer the old calculator. Month: Day: Year e. The following sign conventions are used:. If you select a city from the pulldown menu, the latitude, longitude and time zone fields will be filled in automatically.

There is no one best place for watching sunrise or sunset, just good places and better places. Look for a viewpoint that juts into the canyon with views both east and west. Arrive 30 minutes before the sun clears the horizon and stay an hour or longer after. Dress warmly; even summer dawns can be quite chilly. Plan to arrive at your viewpoint as much as 90 minutes before sunset and stay at least 10 minutes after the sun has set and no longer illuminates the buttes and pinnacles in the canyon, don't rush off —the sky may light up red, pink or orange. Better yet, stay around as the sky grows dark. Grand Canyon offers some of the blackest skies and brightest stars found anywhere. Sunrise: If the night has been calm and clear, sunrise may offer great clarity before breezes stir dust into the atmosphere. Colder morning temperatures and the difficulty of rising early frequently result in fewer people at canyon viewpoints. Sunset: During the summer viewpoints can be crowded. Late summer may bring dramatic thunderstorms, but too many clouds could mean no sunlight in the canyon. Just the right amount of dust or smoke can make a sunset more colorful.

Sunrise and sunset times for past years can be found in the South Australian Government Gazette. Sunrise and sunset times were originally provided as a means of establishing when vehicle lights should be turned on. The published times are computed and are not observed or recorded events. The computations assume certain ideal conditions and the data might not be relevant to a specific case. The times are intended for general public use, not for litigation purposes. They are provided as a prima facie proof of sunrise and sunset and acceptance by a court for other purposes is not guaranteed. The sunrise and sunset times are calculated by interpolation from tables in the Astronomical Phenomena publication for each year.

Our clocks do not keep Sun time. And that is because we have not talked about one other factor in sunrise and sunset times that is not at all obvious. So our clock time neglecting, of course, daylight time shifts is a form of what is called mean solar time. Approximate formulas for the Sun's declination and the Equation of Time are given on our page about computing Approximate Solar Coordinates. The stage of sunrise known as false sunrise actually occurs before the Sun truly reaches the horizon because Earth's atmosphere refracts the Sun's image. On the other hand, the change in the Equation of Time shifts the timing of all Sun phenomena by its full amount. If you are uncertain of the time zone for a location, refer to our Time Zone Table. Six months later, when the Earth is on the opposite side of its orbit, the north pole is tilted toward the Sun by as much as The two effects on sunrise and sunset time might be called, succinctly, the "geometric effect", which is the variation in the length of the Sun's track across the sky as a function of the season; and the "clock effect", caused by the fact that the Sun keeps its own time, which on any given day may be somewhat different from what our clocks say.

We maintain this page as a courtesy to those people who, for whatever reason, prefer the old calculator. If you are uncertain of the time zone for a location, refer to our Time Zone Table. This is what most people even astronomers! Mechanical or electrical clocks run at a uniform rate, and that rate has been set to correspond to the average rate of the Sun across the sky over the course of the year. The Earth's axis of rotation the straight line through the center of the Earth between the north and south poles is not perpendicular to the plane of the Earth's orbit. What Can I Expect to See? The high altitude clouds serve to reflect strongly reddened sunlight still striking the stratosphere after sunset, down to the surface.
