Sunrise and Sunset Calculator (Golden Hour, Twilight, Day Length)
Find sunrise, sunset, solar noon, day length, civil, nautical and astronomical twilight and golden and blue hour for any city or coordinates and date, plus 7 days.
NOAA solar equations with standard refraction (sunrise and sunset when the sun's upper edge touches a flat horizon, 0.833° below). Times are rounded to the minute; hills, buildings and height above sea level shift them by a few minutes.

Sunrise and sunset change every day and depend on latitude, longitude and time zone. This calculator gives them for about 55 major cities or any coordinates, using the equations behind the US NOAA Solar Calculator. It also shows solar noon, day length, the three stages of twilight and the golden and blue hours that photographers plan around, plus a table for the coming week.
How to use this tool
- Pick a city, or choose Custom and type the latitude, longitude and time zone.
- Pick the date.
- Read sunrise, sunset, day length and the twilight and golden-hour windows.
- Use the 7-day table to see how the times shift through the week.
Formula
cos H = cos z ÷ (cos φ cos δ) − tan φ tan δ · sunrise/sunset = 720 − 4λ − EoT ∓ 4H (minutes UTC)
φ is latitude, λ longitude (east positive), δ the sun's declination and EoT the equation of time, both from NOAA's solar position equations. The zenith z is 90.833° for sunrise and sunset (refraction plus the sun's radius), 96°, 102° and 108° for civil, nautical and astronomical twilight, and 84° and 94° for the edges of golden hour (+6° and −4°). If |cos H| > 1 the sun does not cross that altitude that day (midnight sun or polar night). Each time is refined twice with the sun's position at that moment.
Example
In Seoul on 21 June 2026 (the June solstice) the sun rises at 05:11, is highest at 12:34 and sets at 19:57, giving about 14 h 46 min of daylight — the same as the US Naval Observatory's tables. In New York on 21 December 2026 it rises at 07:17 and sets at 16:32: 9 h 15 min. Tromsø, inside the Arctic Circle, has the midnight sun in June and polar night in December.
Frequently asked questions
Why isn't the earliest sunset on the shortest day?
Because the equation of time shifts solar noon later through December. In the mid-northern latitudes the earliest sunset comes in early December and the latest sunrise in early January, though the shortest day is around 21 December.
What is golden hour?
The period when the sun is low (here from 6° above to 4° below the horizon), giving warm, soft light. Blue hour follows at dusk, when the sun is 4° to 6° below the horizon and the sky turns deep blue.
How accurate are the times?
Within about a minute for most places below 60° latitude. Real horizons with hills or buildings, and unusual air temperature, can change the visible sunrise by a few minutes.
