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.

Photographers in Ko Samui get the golden hour at 05:56-06:39 in the morning and 18:14-18:56 in the evening today; the bluish blue hour falls near 05:48-05:56 and 18:56-19:05. Both windows move across the seasons.
