Dusk is the period after sunset. But many people misunderstand it by calling it afternoon or evening. I think personal twilight is the most beautiful time of the day. How not dusk is like a light and dark encounter. As dusk comes we can see the remaining light from the sun blending in with the darkness of the night that is coming. They blend together and make the sky as orange and very beautiful. It differs nuance with dawn. Dawn is the period of time that precedes the rising sun. The indication is that there is weak sunlight while the sun itself is still below the horizon. At that moment the sky looked a little dark.
