The term 'Dusk Period' is also known as 'EVENTIDE', which is an 8-letter word. EVENTIDE is the period of twilight between sunset and nightfall, when the sky is usually a deep orange or pink color. It is a time of day when the sun has set but the darkness of night has not yet arrived. During this period, the light from the sun is still visible, but it is much dimmer than during the day. EVENTIDE is often a peaceful and calming time of day, and many people enjoy watching the sun set during this period.
