Golden hour vs blue hour
Golden hour and blue hour both happen near sunrise and sunset, and they produce very different pictures. Golden hour is warm and directional; blue hour is cooler, softer and more even.

Short answer
Golden hour is the warm, low-angle light shortly after sunrise or before sunset. Blue hour is the cooler twilight light shortly before sunrise or after sunset, when the sun is below the horizon but the sky still has colour.

|---|---|
| Golden hour timing | Shortly after sunrise and shortly before sunset. SunCast’s web tools use the sun between the horizon and 6° up. |
| Blue hour timing | Before sunrise and after sunset during twilight. SunCast’s web tools use the sun between 4° and 8° below the horizon. |

| Blue hour colour | Cool blue, violet or deep twilight tones. |
| Golden hour shadows | Long and directional. |
| Blue hour shadows | Soft, weak or mostly ambient. |
When to use golden hour
Use golden hour when you want warm light with visible direction, shape and texture. It suits portraits, landscapes, city streets, architecture, travel and outdoor products.
The sun is low, so shadows are long and light can wrap across a subject from the side or behind.
When to use blue hour
Use blue hour when you want softer ambient light, city lights, sky colour or a calmer scene after direct sun has gone.
It works well for skylines, streets, interiors with window glow and scenes where harsh direct light would be distracting.
How long each lasts in three cities
The length of both windows depends on latitude, because the sun crosses the horizon at a steeper angle near the equator. In Nairobi the evening golden hour runs from about 18:07 to sunset at 18:37, roughly 30 minutes, and blue hour lasts under 20 minutes. The times barely change between June and December.
In Athens on 21 June, golden hour runs from 20:12 to sunset at 20:52 and blue hour from 21:11 to 21:36. On 21 December the windows are 16:28 to 17:10 and 17:28 to 17:50, so roughly 40 minutes of golden light and 20 to 25 minutes of blue in both seasons.
Helsinki shows how far the pattern stretches. On 21 June golden hour lasts from 21:30 to 22:51. Blue hour starts at 23:44, and because the sun only sinks to 6.4° below the horizon at 01:23, it never reaches the 8° that ends blue hour: blue light lasts until the sun climbs back past 4° below at 03:01. On 21 December the noon sun reaches just 6.4°, so the afternoon golden hour begins at 12:59 and runs to sunset at 15:13 (all times calculated with SunCast’s sun calculator).
Photography examples
Portrait
Golden hour gives skin warmth and directional shape. Blue hour gives a softer mood and mixes well with artificial lights.
City scene
Golden hour lights buildings from the side. Blue hour balances sky colour with streetlights and windows.
Landscape
Golden hour brings out texture and shadow. Blue hour lowers contrast and can make the scene feel quieter.
Limits
Golden hour and blue hour are planning labels with angle definitions that vary between apps. Clouds, mountains, buildings and haze change how the light looks on location.

Frequently asked questions
Is blue hour before or after golden hour?
In the morning, blue hour comes before golden hour. In the evening, blue hour comes after golden hour.
Is golden hour always one hour long?
No. In Nairobi the evening golden hour lasts about 30 minutes all year, in Athens about 40 minutes, and in Helsinki it runs for well over two hours on a December afternoon. The length also depends on the sun angles an app uses.
Which is better for portraits?
Golden hour is often easier for natural-light portraits because it gives warm, directional light. Blue hour suits portraits where you want mood, city lights or artificial light mixed with twilight.
