Sunrise and sunset, city by city

What is on each sun page

Every page gives today's sunrise, sunset, golden hour and the three twilights, a day length curve across the whole year, a month-by-month table, and a first light to last light table. All of it is computed from standard NOAA solar equations at the city's own latitude and longitude, using the usual definition of sunrise and sunset: the sun's centre 0.833 degrees below the horizon, which accounts for refraction and the width of the disc.

Inside the polar circles the sun does not rise or set for part of the year. Those pages say "midnight sun" or "polar night" in plain words rather than printing a time that does not exist. Cities that share a name are listed separately and labelled with their region, so the Valencia in Spain and the Valencia in Venezuela never get confused.

To see the whole terminator at once, the live day and night globe draws the same solar maths across the entire planet, and why seasons happen explains where the swing in day length comes from.
