Sunrise and Sunset Times

Sunrise is the moment when the upper edge of the rising sun appears to be right at the horizon assuming an unobstructed view. That includes the effect of refraction of the sunlight by the atmosphere, which averages about 34 arcminutes. Atmospheric conditions in the sunlight's path to the observer can cause sunrise times to vary by over a minute due to the amount of refraction. At higher latitudes the variation can be many minutes due to the smaller angle between the horizon and the sun's apparent path. For the purpose of calculations, scientists define sunrise to be when the center of the sun is 90.83333° below the observer's zenith. The extra 0.83333°, or 50 arcminutes, accounts for the 34-arcminute average refraction and the 16-arcminute apparent radius of the sun.

The time of sunrise and sunset is very dependent on the date and exact location. A difference of 15 miles can change the time of sunrise or sunset by a minute. Please re-post your question with a city name or zip code.

Sunrise is when the sun appears to rise up from below the horizon (in the morning).

It doesn't, quite. But the difference in the direction of sunrise for the same date each year is so small that you can't really measure it.

As to why the direction remains the same each year, it's because a commission appointed by Pope Gregory in 1582 set up the Gregorian calendar that way. The older Julian calendar (devised, legend says, by Julius Caesar) did not properly adjust the calendar for leap years, and by the year 1570, the conventional calendar in use by the Church was out of synchronization with the seasons. The Gregorian calendar properly adds leap days periodically to the calendar to keep the calendar aligned with the seasons.

So, the same day of the year will correspond, within 3/4 of a day, to the position of the Earth in its orbit around the Sun.

The Pyramid of the Sun in Teotihuacán faces the sunset on August 12. This alignment is thought to be significant to the ancient culture that built the pyramid.

The sun is rising and setting somewhere every minute of every day. You need to specify a city or a set of geographical coordinates.

In Barrow, Alaska today, the sun rises at approximately 1:31 AM and sets at around 1:35 AM due to being located above the Arctic Circle. This results in a period of continuous daylight during the summer months.

Daylight increase is not a linear function.

It is very low at each solstice and equinox, slowly increases to mid term and then decreases again.

Latitude also needs to be taken into account.

Desmond needs to be back before sunrise because, within the game "Assassin's Creed," Desmond relives the memories of his ancestors through a machine called the Animus. If he spends too long in the Animus, it can cause a condition known as the "Bleeding Effect," where the memories of his ancestors start to blend with his own, potentially causing psychological issues.

It depends on how you define the start of the day. If you define according to your work and normal life conditions, then the first salat of the day is the Fajr Salat (at dawn and before the complete sunrise). If you define the start of the day per religion, then the day starts by sunset and the first salat is the Maghrib salat (at sunset and before the full disappearance of sun light).

The sunset in Bryce Canyon, Utah on November 25th, 2010, would have occurred around 5:05 PM local time.

The time of sunrise in Canada varies depending on the specific location within the country. On average, the sun rises between 5:30 AM and 7:00 AM across different provinces in Canada. It is best to check a reliable source for the exact time of sunrise for the particular city or region you are interested in.

no, you can check with online tool, very clever and easy to use is: http://www.sunearthtools.com/dp/tools/pos_sun.php here you obtain the sun path in Cartesian and Polar chart, at any point on the earth at a particular time of day, and time of rise set and noon.

Sunset time on November 11, 2010 in Amelia Island was at approximately 5:36 PM.
