The Days of the Week meaning in astrology

Western civilization has used the 7-day week for about two thousand years. Prior to that, there were other methods of clustering the days together. Around the world, people have found at least fifteen different ways (in bunches of 5 to 10 days) of grouping their days together. The ancient Greeks, it seems, had no week.

Romans lived by an 8-day week. Farmers who worked in the fields for 7 days came to town for the eighth day – the market day. This was a day of rest and festivity, a school holiday, the occasion for public announcements and for entertaining friends. When and why the Romans fixed on 8 days and why they eventually changed to a 7-day week in not clear, but by the early third century A.D. they were living with a 7-day week.

The Naming of the Days

The days of the week are named after the seven ‘planets’ as they were known in Rome two thousand years ago. The days of the week in European languages are still designated by the planets’ names. Our familiar order of the names for the days of the week came from the order of the planets that the Romans thought governed the first hour of each day.

The astrologers of the day made use of the order of the planets according to their supposed distance from the earth to calculate the influence of each planet on worldly affairs. They believed that each planet would govern an hour, then in the next hour, would give way to the influence of the next planet nearer the earth, and so on through the the cycle of all seven planets. After each cycle of seven hours, the planetary influences would begin all over again in the same order. The governing planet for each day, then, was the planet that presided over the first hour of that day, and each day of the week thus took its name from the planet that governed its first hour.

So it is that each day is imbued with the quality of the planet after which it is named. We can recognize and use the qualities of each day and the natural cycle of the week beyond the typical school- or work-oriented week to accomplish our goals and fulfill our dreams, while gaining a sense of being in sync with the natural order of daily activities.

The optimum time for tuning into the day’s energy is at dawn. It is in the growing light that the promise of the day is made. Journal writers can use the quality of the days as starting points or topics for the day. If you have been keeping a journal, look back through your pages. How does the quality of the day show itself?
