In polite company we accept these generalizations, handing down the judgment of day with only the evidence of a moment, simply because most people do so, though technically only Day Accountants are qualified to assess all variables of a day's morality. For instance, even with all of the world's illness, despair, unemployment, harm, riot, war, and famine, last Tuesday was a good day, given all of the rain puddles stomped worldwide.
The wisest of Day Hierophants find it difficult to pass such vituperative and final dismissals of days, even when they are commonly judged as bad, and will petition the heavens to be more understanding. While most people judged Thursday a bad day, it was technically recorded as a lanky, clumsy day of suspect morality which was not caught red-handed, but which was probably lying.
