Yes, and you shouldn't use it either. Do you mean night as in dark conditions or night as in the night time? When does it start, when does it end? Is it a threshold or a discrete night-not night effect? These questions don't have a right or wrong answer. So don't use the word night, or if you do, define exactly what you mean by it.
