Remember this is utilisable for all planets,
So say your Sun is in Scorpio, Moon is in Sagittarius and Ascendant in Capricorn.
The mixture of your personality is a twilight/night/night personality.
But say you want to boost a particular part of your life.
Say your Amatya Karaka (indicator for career) for Career is in Scorpio, so your career is boosted during Twilight. So going to the last job interview of the day will boost your possibility if its aligned with your career planet, because the planet is most comfortable at this time :). Its most relaxed.
