Golden Hour & Blue Hour Calculator

Blue hour occurs when the sun is between -4° and -6° below the horizon (some definitions use -12°). The sky takes on a deep blue hue, perfect for moody cityscapes and tranquil landscapes. Our calculator shows the period between nautical and civil twilight as the blue hour window.

We use the reliable sunrise-sunset.org API and precise twilight definitions. Times are converted to your local timezone. While minor atmospheric refraction can shift actual light by a few minutes, the times are accurate enough for photography planning.

Absolutely. Enter any latitude and longitude, or search for a city name. The tool works for all places on Earth, even remote areas. Just ensure coordinates are valid.

Yes. Near the equator golden hour lasts around 20-30 minutes, but at higher latitudes it can exceed an hour in summer. The calculator automatically accounts for these variations based on the exact date and location.
