What is the Sunrise, Sunset & Moon Phase Calculator?
Enter a city, your location or exact coordinates, pick a date, and see when the sun rises and sets, solar noon, the length of the day, and the three twilight periods — civil, nautical and astronomical — plus golden hour, the best time for warm, soft photography. A curve shows how high the sun climbs through the day. Near the poles the calculator tells you when there is midnight sun or polar night.
The moon section shows tonight's phase name, the percentage of the disc illuminated, the moon's age in days, a drawing of its shape, and the exact date and time of the next new moon and full moon in the place's own time zone. The sun uses the NOAA solar equations and the moon uses Meeus's astronomical algorithms, computed in your browser with no data sent anywhere.

Questions people ask
How accurate are the times?
Sunrise and sunset are typically within about a minute; accuracy drops close to the poles.
What is civil, nautical and astronomical twilight?
The sun is 6°, 12° and 18° below the horizon: civil is enough light to see outdoors, nautical is horizon still visible at sea, astronomical is fully dark sky.
What is golden hour?
The period after sunrise and before sunset when the sun is low and light is warm and soft — the favourite time for photographers.
Why does it say midnight sun or polar night?
Above the Arctic and Antarctic circles the sun can stay up or down for 24 hours around the solstices.
Does it show moonrise and moonset?
Not yet. It shows phase, illumination, age and the next new and full moon.
