The Golden Hour App has often served me well to know the exact time of the golden and blue hour in advance. With it you can not only plan when you are going to take pictures in the next days. Likewise, especially when planning photos for your upcoming holidays, you can use the app to arrange with your travel companion which evening you will take the picnic to the beach and at what time.
The app tells me exactly that if today here in Bristol the sunrise is at 7:09 am, then the blue hour is from 6:23 am to 6:49 am. Unfortunately, that’s much shorter than one hour, namely only 26 minutes. The golden hour, on the other hand, is actually longer than one hour and lasts today from 6:49 to 7:54, that is, half an hour before sunrise until almost an hour after sunrise.
And the other way round, of course, there is the evening. There the golden hour begins about one hour before sunset and ends half an hour after sunset. Then the rather short blue hour begins, in which everything appears bathed in an incredible blue.
