In Europe we have chosen the second course, but at the price of parting with the moon, so that our 12 months, while forming a convenient subdivision of the year and an adequate guide to the seasons, have no relation to the planet from which they receive their name. We have also subdivided our day into hours and, at a later time, into minutes and seconds, arbitrary subdivisions indeed, but still forming a system, so that a year consists of a fixed number of complete months, a month of complete days, though in varying numbers, and days of a fixed number of complete hours.
Across this ordered system runs that intruder the week, consisting indeed of a fixed number of complete days, but paying no regard to months or years. The moment that begins a new year, begins also a new month, a new day, and a new hour, but only once in five years, at the least, a new week. It is very frequently and indeed, I think, generally assumed that this continuous week somehow represents the four phases of the moon. It is true that the course of the moon naturally to the eye of the observer groups itself into quarters and that if 2912 be divided by 4 the nearest integral number is 7 and the next nearest 8. It is also true that the three early varieties of the week, of which we have any knowledge, the Jewish, the Planetary, and the old Roman, consist of either seven or eight days. But at the same time it is obvious that continuous
