Sun & moon
Sunrise, sunset, the golden hour and the phase of the moon, anywhere on Earth. Each tool has its own page. It runs in your browser, and it keeps its inputs in the address bar so you can share the answer.
The tools
Sunrise and sunset times, golden and blue hour, solar noon, day length, moonrise and the moon's phase, for any place on Earth and any date you pick.
Sunrise CalculatorSunrise for any place and date, with the twilights before it, the bearing the sun comes up on, and how much earlier or later it is than yesterday.
Sunset CalculatorSunset for any place and date, the twilight that follows, the bearing it goes down on, and how long you have before it is properly dark.
Golden Hour CalculatorThe two windows a day when the sun is low and the light is warm — with the exact start and end, and how long you actually get, which near the equator is not an hour.
Blue Hour CalculatorThe window before dawn and after dusk when the sky is deep blue and lit buildings balance it — the sun between -6° and -4°, twice a day.
Moon Phase CalculatorThe phase for any date, drawn as well as named, with the illuminated fraction, the moon's age in days, and the dates of the next new and full moons.
Moonrise CalculatorMoonrise for any place and date, with the phase and how much of the disc is lit — and an honest answer on the days when the moon does not rise at all.
Moonset CalculatorMoonset for any place and date, with the phase, the time it spends above the horizon, and the days it does not set at all.
Solar Noon CalculatorTrue solar noon for your location — usually nowhere near 12:00 on the clock — with the sun's altitude at that moment and the shadow length it casts.
Day Length CalculatorHours of daylight for any place and date, how much it changed since yesterday, and the longest and shortest days of that year at that latitude.
Night Length CalculatorDarkness for any place and date — from sunset to sunrise, and separately the true astronomical night, which at high latitudes disappears entirely in summer.
