Using the Sun Times Tool

The Sun Times tool calculates sunrise, sunset, solar noon, day length and golden hour for any location, plus this year's solstices and equinoxes, using solar-position maths that runs entirely in your browser. These guides go beyond the interface itself: they cover how day length changes with latitude and season, why solar noon rarely lines up with 12:00 on your clock once time zones and daylight saving are involved, and how golden hour and blue hour are defined relative to sunrise and sunset rather than as fixed clock times.

If you shoot photos or video outdoors, timing matters more than almost anything else: the golden-hour guide explains why the light during the hour after sunrise and before sunset is so much softer and warmer than midday sun, how that window stretches or shrinks depending on latitude and time of year, and how to use the sun times here alongside the weather forecast to check for clear skies before you plan a shoot, and how the same day-length numbers explain why summer evenings stay light so much later at higher latitudes.
