While it may seem like they are in a random order, it is actually a somewhat complicated
formula. Each day is divided into 24 hours. This is determined by the time from
Sunrise to Sunset divided by 12, and the time from Sunset to the following Sunrise
divided by 12. The planetary rulers of each hour follow the Chaldean order. This
is the order of the planets from Saturn to Moon according to their increasing average
daily motion. Chaldean order of the planets is: Saturn, Jupiter, Mars, Sun, Venus,
Mercury, Moon. Therefore, Saturn's hour is followed by Jupiter's hour and so on.
The planetary rulers for the days are determined by what planet rules the hour of
Sunrise. In planetary rulerships, a day is not Midnight until the following Midnight.
A day is Sunrise until the following Sunrise. Each day, we cycle through the 7
planets used three times each, and then the first three planets in another cycle
for a total of 24 hours (a threefold cycle). The next planet in order is the ruler
of the Sunrise hour for the following day, and therefore the ruler of the following
As an example: Saturday begins with Saturn ruling the hour of Sunrise. Hours 1(Sunrise)
- 7 takes us through a complete Chaldean cycle. Hours 8 - 14 and 15 - 21 completes
2 more cycles in the Chaldean order. That leaves Saturn ruling the 22nd hour, Jupiter
ruling the 23rd hour, and Mars ruling the 24th hour. That completes Saturday, and
brings us to the first hour of the following day. It is ruled by the next planet
in the Chaldean order, the Sun. Because the ruler of the Sunrise hour becomes the
ruler of that day, the Sun's day (Sunday) follows Saturn's day (Saturday). This
continues in an unending pattern, giving us the daily ruler that our weekdays were
HOWTHE PLANETARY HOURSAND DAYSARE USED
This is one of the most basic applications of astrology. The energy of the planet
ruling the day is increased on that day. Likewise, the energy of the planet ruling
the hour is stronger during that hour. This gives astrologers deeper insight into
the influences of a specific time. It is also a way to select a time (in electional
astrology) with more appropriate energies even if the ruling planets aren't strongly
aspected. You will have strong Mars energy during Mars hour on a Tuesday, even with
a weak Mars placement. This can also be used for combinations of planetary energy.
For example, if you are planning a date Mars - Venus is a classic romantic combination.
Try a Mars hour on Venus day - this is always easy to determine, Mars rules Sunset
and the following hour on Friday evenings!
The use of planetary hours and days can be applied, even by non-astrologers. Our
planetary hour charts have a keyword guide at the bottom of each page. When planning
any activity, choose a combination of hour/day with ruling planets whose energy seems
appropriate for a more successful outcome. This method has long been used by gardeners
and herbalists. Planting as well as harvesting can be more productive if you choose
the hour/day of the planet ruling the specific plant in question. This method, combined
with Moon phases, and Moon signs can give you amazing results! For herbs, harvest
during the hour ruled by the planet reflecting the intended use of that herb.
There is an unlimited amount of uses for this method in spiritual matters. Meditation
and chakra work can be greatly enhanced this way. See our chart of planetary rulers
of the chakra. Whatever chakra is ruled by the planet who is ruling the current
day or hour is more active. For Wiccans and Pagans, use of planetary hours and days
is quite traditional. The most effective spells and rituals are performed on the
appropriate day, at the appropriate hour. Some consider this as important as the
Moon's sign. Anything you make yourself such as incense, magickal waters, amulets,
talismans and so on can be given added strength by choosing the best time to make
