So do your chores during the day, problem solved, if you don't like facing the tougher mobs at night. Seems logical. The game has a difficulty curve, things do get harder as you progress, more dangers/challenges. If you just want peace and quiet then don't kill the bosses. Otherwise yes, at night some harder things will show up. Sleep at night, adventure during the day, then the night issues are irrelevant if they disrupt your peaceful easy feeling.
