Golden Hour Photography Calculator

Introduction: Plan morning and evening golden hour

Golden hour is the low-angle light shortly after sunrise and shortly before sunset. This calculator estimates those windows for a latitude, longitude, and date so you can plan arrival time, subject placement, and backup shots before the light changes.

The page first estimates sunrise and sunset from solar position formulas. It then reports the morning golden-hour start as roughly one hour after sunrise and the evening golden-hour start as roughly one hour before sunset. That simple convention is useful for planning, even though haze, mountains, buildings, and weather can shift the usable light.

Formula approach

The script uses the date, latitude, and longitude to estimate solar transit, sunrise, and sunset. It then applies:

Morning golden hour = sunrise + 1 hour.

Evening golden hour = sunset - 1 hour.

How to use the result

Enter coordinates for the shooting location, not your hotel or home base. If you are photographing in a canyon, dense city street, forest, or behind a ridge, arrive earlier and scout the actual light. For portraits, plan the pose and background before the reported window begins. For landscapes, use the result to decide when to set up, then watch the sky rather than the clock alone.

Limitations

This is a practical planner, not a full astronomical almanac. It does not model terrain shadows, cloud cover, air quality, daylight saving rules beyond the browser's local time handling, or the exact solar elevation range some photographers use for golden hour.

Worked example: compare one realistic scenario

Enter a realistic value for Latitude, keep the other fields at normal operating values, and record the result. Then change only date and rerun the calculator. The difference shows which assumption deserves attention.
