Golden Hour Calculator
Find the exact start time of the golden hour based on your local sunset time. Perfect for landscape and portrait photographers planning shoots around the best natural light.
About this calculator
The golden hour refers to the period roughly one hour before sunset when the sun is low on the horizon, producing warm, soft, diffused light that is highly prized in photography. This calculator converts your local sunset time into total minutes, then subtracts 60 minutes to find the golden hour start time: Golden Hour Start (minutes from midnight) = (sunsetHour × 60 + sunsetMinute) − 60. The result is then converted back to hours and minutes for a human-readable time. During golden hour, the sun's light travels through more of the atmosphere, scattering short blue wavelengths and leaving warm reds and oranges. The exact duration varies by season and latitude — it can last well under an hour near the equator and extend for over an hour at high latitudes.
How to use
Sunset is at 7:45 PM (19:45). Step 1: Convert sunset to total minutes — 19 × 60 + 45 = 1185 minutes from midnight. Step 2: Subtract 60 — 1185 − 60 = 1125 minutes. Step 3: Convert back — 1125 / 60 = 18 hours and 45 minutes, or 6:45 PM. Golden hour begins at 6:45 PM and runs until sunset at 7:45 PM. Plan to be on location at least 15 minutes early to set up your shot.
Frequently asked questions
What exactly is the golden hour in photography and why does the light look different?
Golden hour is the first and last hour of sunlight in a day, when the sun sits close to the horizon. At this angle, sunlight travels through a much thicker slice of atmosphere compared to midday, which scatters short-wavelength blue light away and lets long-wavelength warm orange and red light reach the ground. Shadows are long and soft, contrast is low, and the overall scene takes on a flattering warm tone. These conditions are ideal for portraits, landscapes, and architecture photography.
How long does golden hour actually last and does it vary by location?
Despite its name, golden hour does not always last exactly 60 minutes. Near the equator, the sun drops steeply below the horizon and golden hour can last as little as 20–30 minutes. At high latitudes — such as Scandinavia or Alaska in summer — the sun moves at a shallow angle and the golden light can persist for two hours or more. Season also matters: in winter, the sun stays low all day at mid-latitudes, extending soft light well beyond a single hour.
How is golden hour different from the blue hour for photography?
Blue hour occurs just after sunset (or just before sunrise) when the sun is between roughly 4° and 8° below the horizon. During blue hour, the sky takes on a deep, even blue tone as diffuse indirect sunlight still illuminates the sky without any direct sun in frame. It is ideal for cityscape and architecture photography where artificial lights balance beautifully with the ambient sky. Golden hour, by contrast, occurs while the sun is still above the horizon and produces warm directional light with visible shadows, making it better suited to portraits and landscapes.
