Pronunciation: /ˈkrepəˌskyo͞ol
(also crepuscle /ˈkrepəsəl/)
noun
• rare
Twilight.
Origin
late Middle English: from Latin crepusculum 'twilight'.
---------------------------
Something tells me that the recent vampire/werewolf movies from Stephanie Meyer's books would not have done quite so well if titled "The Crepuscule Saga." The more modern term Twilight is appropriate, as such movies are not rare.
[For what it is worth, I prefer the blooming light of anticipation at dawn over the crepuscular, fading colors of dusk.]
