What is the least amount of words you can use in a word chain when starting from "Dawn", using "Noon" in the middle, and finishing with "Dusk", and using only 4 letter words? Please try to stick to "regular" words (i.e. something found in the dictionary or that would be used in a crossword, no abbreviations).
Example word chain:
