Understanding Twilight & the Golden Hour
After the sun drops below the horizon, the sky does not turn dark all at once. Civil twilight is the brightest stage, when there is still enough natural light for most outdoor activities. Nautical twilight follows, when the sea horizon becomes hard to make out. Astronomical twilight is the darkest stage, after which the sky is fully dark and the faintest stars appear. The same three stages occur in reverse before sunrise, as dawn.
In Guyancourt today, the morning golden hour runs 06:59-08:00 and the evening golden hour 19:36-20:37, with the cooler blue hour around 06:47-06:59 and 20:37-20:49. These warm and cool light windows drift through the year as the sun's path changes.
