Lumen Hour: Golden Hour & Sun

Never miss the best light of the day: a live countdown to golden hour, sunrise and sunset bearings, and a planner for any city.

Lumen Hour tells you exactly when the most beautiful light of the day arrives, and where it will come from.

• LIVE COUNTDOWN to the next golden hour, down to the second. The card turns warm the moment golden hour begins • SUN PATH CHART: the sun's height through the whole day, with golden and blue hour bands and a marker for right now • EVERY KEY TIME: sunrise, sunset, morning and evening golden hour, morning and evening blue hour, solar noon with its altitude, and day length • BEARINGS: a compass that shows where the sun rises and sets today and where it is right now. It turns with your phone when you hold it flat • SHADOW LENGTH: how long shadows are right now, as a multiple of height • MOON PHASE: illumination and days until the full moon • PLAN A SHOOT: pick any date and any of 33 photo cities, from Seoul and Jeju to Santorini, Reykjavik and the Grand Canyon, and see the next two weeks of evening golden hours • ALERTS: optional reminders 10 to 60 minutes before morning or evening golden hour • Handles midnight sun and polar night

Times are calculated on your device with the NOAA solar position algorithm. Terrain and weather are not taken into account.

No ads, no account, no tracking. Your location is used only to calculate the sun's position, and you can choose a city instead.
