The name Tuesday comes from the Germanic God Tiu, like the Roman god Mars, is associated with war. Like Monday, it is full of male energy, but focuses on the more raw nature of the male aspect; think courage, success, war, and lust. This is a good time to deal with issues of violence, competition, conflict, endurance, and survival.
