Please note that posts on this site may contain affiliate links

Planetary hours and planetary days are an ancient methodology of choosing the best time to do magic or other activities based on what planet rules that time. It was developed within Hellenistic astrology but likely has roots in older Babylonian astrology. 

You use the planetary days and hours to conduct business, cast spells, and create talismans during auspicious times based on planetary rulerships. The planetary hours and days were used by ancient Hellenists as well as Babylonians to determine when certain events would occur. For example, if you wanted to know when Jupiter would be most favorable for making money, you could look at the planetary hour and day of Jupiter.

Many grimoires like the Hygromanteia include tables of planetary days and hours that can be useful for modern occultists and witches.

The Planetary Days

The planetary rulership of some of the days of the weeks is very clear. Monday is ruled by the moon, Saturday by Saturn, and Sunday by the sun. Planetary days and hours are based on the classical planets, which includes the sun and moon but not the outer planets like Uranus and Pluto.

Here are the traditional planetary rulers of the days:

How To Calculate Planetary Hours

Calculating which of the traditional planets rules an hour of the day is simple.

From Wikipedia:

As each day is divided into 24 hours, the first hour of a day is ruled by the planet three places down in the Chaldean order from the planet ruling the first hour of the preceding day; i.e. a day with its first hour ruled by the Sun (“Sunday”) is followed by a day with its first hour ruled by the Moon (“Monday”), followed by Mars (“Tuesday”), Mercury (“Wednesday”), Jupiter (“Thursday”), Venus (“Friday”) and Saturn (“Saturday”), again followed by Sunday, yielding the familiar naming of the days of the week.

Calculating the favorable times to do something can become complicated, however. Luckily, magicians and witches before us left tables that we could easily reference! 

The Magical Treatise Of Solomon or Hygromanteia by Ioannis Marathakis has the tables from multiple fragments of this old grimoire. The most fully preserved tables come from the Gennadianus manuscript. The tables below will mostly come from the Gennadianus except where it had missing information, which will be filled in from the Monacensis or Harleianus manuscripts.
