Sunrise and Sunset Calculator

Our sunrise and sunset calculators show not only the sunrise and sunset, the time of the moon and the moon, but also the rising and setting times of the planets

Calculator displays time in USA and Canada; just enter your zip code or postal code to see the sunrise and sunset times in your area

Planetary (and dwarf) generation and settling time: Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto

Since sunrise and sunset are calculated not from the center but from the front and back edges of the sun, the duration of the day is slightly longer than the night (about 10 minutes from the warm latitude). In addition, the light from the sun will refract as it passes through the Earth's atmosphere, so the sun will be visible even after the geometry is below the horizon. When the sun is very close to the horizon, refraction also affects the apparent shape of the sun. It makes the sky look higher than they actually are. The light from the lower end of the solar disk refracts more than the upper light because the refraction increases as the elevation angle decreases. This allows the bottom edge to be significantly larger than the top, thereby reducing the apparent height of the solar panel. Because its width does not change, the disc looks higher than that. (Actually, the sun is almost completely spherical.)

You can see that the sunset and sunrise from December to Sunday is longer than from June to the day. The sun in December is closer to the earth than June. Therefore, the December sun disk looks bigger in our sky, so it will take some time to set up. Also, moving closer to the ecliptic in December will move eastward at a faster rate, so it will help slow down the speed from December to sunset (and sunrise). For example, at northern latitude 50 degrees, the sunrise (sunrise) of the winter solstice lasts about 4 minutes 18 seconds and it is about 8 seconds longer than the sunrise (sunrise) of the summer solstice.
