Decanates – Days of the week


The ancients listed the planets in the order of their apparent orbital speed around the earth. This is often referred to as ‘The Chaldean Order’.

This order begins with Saturn which has the slowest orbital speed of approximately 29 years to the fastest planet which is the Moon which takes about one month to orbit the earth.

The order is Saturn, Jupiter Mars Sun Venus Mercury and the Moon.

If you are new to astrology please note that the lights (the Sun and the Moon) are referred to as ‘planets’ – the word planet comes from the Greek meaning moving star. Astrologers of course understand that the Sun is a star and the Moon a satellite of the earth.

It is interesting that the Sun is placed in the centre of this planetary order – astrologers have known for a very long time that the Sun is the centre of the solar system.

This Chaldean order is used for the 7 “ages of man”, the 7 days of the week, as a means of understanding the 12 houses of the zodiac, the minor essential dignities called ‘face’, etc. .


The decanates are a division of the zodiac signs into equal divisions of three. Since there are 30 degrees in each sign, each decanate contains ten degrees.

In the adjacent image the decanates are shown beneath the Chaldean order of the planets. In the horizontal rows of this table are shown the planetary rulers of each decanate beginning with Mars as the 1st decanate ruler of Aries. Following Mars, in the Chaldean order of the planets is the Sun, then Venus, followed by Mercury at the beginning of the row for Taurus, and so on.

Days of the week

It is interesting that when this order of planets is read vertically down the column, the planets follow the order of the days of the week: Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn.

Sunday is the day of the Sun, Monday is the day of the Moon, Tuesday is ruled by Mars (named after the Scandinavian god Tyr); Wednesday is ruled by Mercury (named after the Scandinavian god Woden); Thursday is ruled by Jupiter (named after the Scandinavian god Thor); Friday is ruled by Venus (named after the Scandinavian god Frigg); and Saturday is the day of Saturn, the last day of the week.

The first column begins with Mars (Tuesday), followed by Mercury (Wednesday), Jupiter (Thursday), Venus (Friday); and so on. The middle column begins with the Sun (Sunday), followed by the Moon (Monday), Mars (Tuesday), Mercury (Wednesday); and so on. The third column begins with Venus (Friday), followed by Saturn (Saturday), the Sun (Sunday); and so on.
