How Sunrise and Sunset Times Are Calculated
Sunrise and sunset depend on a location's latitude and longitude and the date. This tool uses standard astronomical formulas (the same NOAA solar equations used by observatories) to compute the exact times, plus day length, twilight phases and golden hour, for any city on any date.
Twilight and Golden Hour
- Civil twilight — the soft light just before sunrise and after sunset when it is still bright enough to see.
- Golden hour — roughly the first hour after sunrise and last hour before sunset, prized by photographers for its warm, soft light.
Daylight Saving and Polar Regions
Times are shown in the city's local time and account for daylight saving. Near the poles the sun may not rise or set at all on some dates (polar day or polar night), which the tool indicates.
Frequently Asked Questions
They are computed from the city's latitude, longitude and the date using standard NOAA solar formulas, then shown in the local time zone with daylight saving applied.
Golden hour is roughly the first hour after sunrise and the last hour before sunset, when sunlight is warm and soft — the light photographers prefer.
Near the poles, the tilt of the Earth can keep the sun above the horizon for 24 hours in summer (polar day) or below it in winter (polar night). The tool flags these cases.
