How accurate is the calculator?

Results are accurate to within about one minute for most locations and dates. The calculator uses the NOAA solar position algorithm; atmospheric refraction and elevation differences account for the small remaining error.

What is civil twilight?

Civil twilight is the period when the sun is between the horizon and 6 degrees below it. It is still light enough to work outdoors without artificial light.

Why does the page say the sun never rises or never sets?

At extreme latitudes around the summer and winter solstices, the sun can stay above the horizon for 24 hours (polar day) or below it for 24 hours (polar night). The calculator flags these cases.

Why is solar noon not exactly at 12:00?

Two reasons: the equation of time (up to ±17 minutes seasonal offset between mean and actual solar time), and your longitude offset from the centre of your timezone. Both are accounted for in the calculation.

How to calculate sunrise and sunset times

Enter coordinates and a date, or use your device location, to get sunrise, sunset, solar noon, civil twilight, and golden-hour times.

Enter a latitude and longitude in decimal degrees. Positive values are north and east, negative are south and west.
Pick the date you want to compute times for. The calculator accepts any past or future date.
Optionally press Use my location to fill in the coordinates automatically from your device. Your browser will show a permission prompt.
Read the results: sunrise, sunset, solar noon, civil dawn, civil dusk, and day length appear in cards. Times are shown in your browser’s local timezone.
Check the Golden hour card for the approximate warm-light windows at sunrise and sunset, useful for photography.
