What golden hour is
Golden hour is the short window just after sunrise and just before sunset when the sun sits low and its light turns warm, soft, and golden. Shadows grow long, contrast drops, and ordinary scenes look cinematic without any editing. Photographers plan whole shoots around it, and for good reason: the same street, face, or landscape photographed at noon looks flat, while at golden hour it glows. The problem is that golden hour moves every day and differs by location, so guessing its time wastes the best light of the day.
This calculator uses SunCalc, a well-known sun position library, to compute the golden hour windows for the date and location you enter. It needs your latitude and longitude, which you can find by right-clicking any spot on a map application. Enter the date of your shoot, and it returns the morning window, from sunrise to the end of the morning golden hour, and the evening window, from the start of the evening golden hour to sunset, along with sunrise, sunset, solar noon, and the total day length. Times are shown in your device’s time zone.
Why the light is golden
When the sun is low, its light travels through much more atmosphere than at noon. Air scatters blue light away, which is why the sky looks blue, and the light that reaches you is stripped of blue and rich in warm reds and golds. The long path also softens the light: shadows lose their hard edges, skin looks smoother, and landscapes gain depth. This is physics, not a filter, which is why no editing preset quite reproduces it. The effect is strongest when the sun is within a few degrees of the horizon, which is exactly the window the calculator shows.
Clouds change everything, and not always for the worse. A clear sky gives clean golden light but can look empty. Thin high cloud catches the warm light and turns pink and orange, which many photographers prefer. Thick low cloud blocks the sun entirely and there is no golden hour at all, whatever the calculator says. Always check the forecast alongside the times: the calculator tells you when to be ready, the sky decides what you get.
A worked example
Take London on a summer day, 21 June. Sunrise is around 4:45 in the morning and sunset near 9:20 in the evening, giving a very long day. The morning golden hour runs from sunrise to roughly 5:45, and the evening golden hour from about 8:20 to sunset. That is a generous pair of windows, but the morning one demands a very early start, which is why most photographers favour the evening session. In winter the picture flips: sunrise near 8:00 and sunset near 4:00 give short days, but golden hour lands at sociable times, and the low sun stays golden for much of the day.
Latitude matters just as much as season. Near the equator, the sun rises and sets almost vertically, so golden hour is short, sometimes barely thirty minutes. At high latitudes in summer, the sun slides along the horizon for hours, and golden hour stretches into a golden evening that barely ends. If you travel for photography, run the calculator for your destination before you pack: the light you expect at home may behave very differently where you are going.
Planning a golden hour shoot
Arrive early. For an evening session, be in position at least thirty minutes before the golden hour starts, because the light changes fast and the best compositions take time to find. Scout the location in advance if you can, and know where the sun will set relative to your subject: a portrait wants the sun behind or beside the subject, a landscape often wants it ahead, lighting the scene you face. Bring a lens cloth, because low sun exposes every speck of dust as flare.
Shoot quickly and vary your angles. The light at the start of golden hour is brighter and more neutral, while the last minutes before sunset are deeply warm and dramatic. Both are worth having. If you shoot portraits, a simple reflector or a gentle fill flash stops faces going dark against a bright sky. And keep shooting a few minutes past sunset: the afterglow that follows is often the most colourful light of the day, and it costs nothing but patience.
Frequently asked questions
How long does golden hour last? Usually about an hour after sunrise and an hour before sunset, but it varies with latitude and season, from under half an hour near the equator to several hours at high latitudes in summer.
Is golden hour the same as sunset? No. Sunset is a moment, golden hour is the window around it. The calculator separates the two so you can plan for the whole window, not just the final minute.
What if it is cloudy? Thin cloud often improves golden hour by colouring the sky. Thick cloud removes it. The calculator gives times, not weather, so pair it with a forecast.
Golden hour times are computed for the location and date you enter and are approximate: hills, buildings, and weather shift the real light. Use the calculator above to plan, arrive early, and let the low sun do the work it has done for photographers since the first cameras.
