Planning Around the Light, Not Just the Clock

Golden hour and blue hour don’t happen at fixed times — they shift with the date, your latitude, and how far the sun travels below the horizon at your location. A generic “shoot an hour before sunset” rule of thumb breaks down fast outside of mid-latitudes. This tool calculates the real windows from actual sun-position math for your exact coordinates and date.

Golden Hour vs. Blue Hour

Golden hour spans roughly from sunrise (or from 6° above the horizon before sunset) through about an hour after sunrise, and the mirrored window before sunset — when the sun’s low angle produces warm, directional, flattering light. Blue hour follows, when the sun sits between 4° and 6° below the horizon and the sky itself becomes the dominant light source, giving that deep saturated blue often used for cityscapes and architecture.

Why the Windows Change by Season and Latitude

Near the equator the sun rises and sets almost vertically, so these windows are short and consistent year-round. Farther from the equator, the sun crosses the horizon at a shallow angle, stretching golden and blue hour out — sometimes to 30 minutes or more each, and considerably longer near the solstices at high latitudes.

This tool is especially useful for:

• Location scouts and photographers planning a call time around exact light windows.
• Traveling shooters working at unfamiliar latitudes where rules of thumb don’t apply.
• Production schedulers building a shot list around limited natural light.
