How it works
Each city's exact coordinates determine the angle of sunlight throughout the year.
We use the NOAA solar position algorithm to calculate the sun's position relative to your location.
The calculations account for atmospheric refraction, which makes the sun visible slightly before it crosses the horizon.
Frequently asked questions
Sunrise and sunset times are calculated using the NOAA solar position algorithm, which takes into account your latitude, longitude, and the date. The algorithm accounts for atmospheric refraction and the apparent size of the sun.
Dawn (civil twilight) begins when the sun is 6 degrees below the horizon and the sky starts to brighten. Sunrise is when the top of the sun first appears above the horizon. Dawn is typically 20-30 minutes before sunrise.
Sunset is when the last part of the sun disappears below the horizon. Dusk (civil twilight) ends when the sun is 6 degrees below the horizon and the sky becomes fully dark. Dusk is typically 20-30 minutes after sunset.
Sunrise and sunset times change because the Earth is tilted 23.5 degrees on its axis. As the Earth orbits the Sun, different parts of the planet receive more or less direct sunlight, causing seasons and varying day lengths.
Solar noon is when the sun reaches its highest point in the sky for the day. It is typically a few minutes off from 12:00 clock time due to the analemma (the sun's apparent position varies throughout the year).
