When the Sun comes up, when it goes down, and the best light in between.
Your answer
Select your place and a date to fill this section with sunrise, sunset, golden hour and blue hour, and a table of the month from first light to last light each day.
The working
Sunrise and sunset are the moments the Sun's upper edge touches a flat horizon. Because air bends the light, that happens when the Sun's centre is still 0.833° below the horizon. Civil, nautical and astronomical twilight end when the centre is 6°, 12° and 18° below. Golden hour here is the Sun between 6° above and 4° below the horizon, and blue hour between 4° and 6° below. The times come from Astronomy Engine searches for your latitude and longitude, in the place's own clock time.

Questions
The moment the top edge of the Sun touches a flat horizon. Air bends the light, so at that moment the Sun’s centre is really 0.833° below the horizon. This is the standard used by the US Naval Observatory and NOAA.
The time when the Sun is low, from about 6° above the horizon to 4° below, giving warm light and long shadows. It comes just after sunrise and just before sunset, and lasts longer the further you are from the equator.
They end when the Sun is 6°, 12° and 18° below the horizon. Civil twilight is bright enough to work outside; nautical twilight is when sailors could still see the horizon; after astronomical twilight the sky is fully dark.
Because solar noon drifts later through December, as the Earth’s orbit is not a perfect circle. In London the earliest sunset is around 12 December and the latest sunrise around 30 December, either side of the 21 December solstice.
In summer the Sun can stay up all day (the midnight sun), and in winter it can stay down all day (polar night). In Tromsø, Norway, the Sun does not set from about 18 May to 24 July. The calculator says so instead of giving a time.
Within about a minute of almanac tables for a flat, clear horizon at sea level. Hills, buildings, height above sea level and unusual air can change what you actually see by a few minutes.
