6:00 is the start of sundown. For certain Christian & Juedeo sectors who acknowledge the biblical sabbath, or the seventh day of the creation week, to rest and worship from “sundown to sundown”. How it is observed and interpreted changes by religion; however, 6:00 pm is generally thought to be used as the standard practice of sundown.
This brings a unique thought experiment for time - when does a day start and when does it end? In a scenario like honoring the sabbath, 6:00pm represents the beginning of a reflection period while also marking the end of one. Plus, 6 pm is not always the literal time when the sun sets below the horizon, begging the question, what do we represent as time?
