Some witches, mainly Wiccans I believe, do their spellwork
on certain days of the week, depending on the theme of the spell. They
believe that the day of the week holds a special significance to the theme
of their spell.
Here are the weekly planetary correspondences. You can use
these to determine which days of the week you may have better luck with
the spells you are casting.
Monday: The Moon; best for emotionally based spellwork, such us attracting
confidence and intuition, protection spells, clairvoyance etc..
Tuesday: Mars; great for spells to inspire passion and energy such as a
spell to boost confidence. Mars is a warrior, so if you need a spiritual
battle, this is the day for it. Tuesday is also a good day for protection
Wednesday: Mercury; Great for communication (worldly or otherwise). Good
for spells involving the granting of information. Like Willow in Buffy
when she says "Reveal!"
Thursday: Jupiter; probably the best day for spell work as Jupiter is so
benevolent and loves to give. All prosperity spells or luck and success
spells should be done on this day (be sure to keep it with the waxing
Friday: Venus. . .ahhh, sweet love. This is a day for love spells and also
a good day to offer your love to the gods/goddesses of choice. As the Cure
say, "Friday, I'm in Love!"
Saturday: Saturn. A restrictive energy. Good for banishing spells and
ridding old energies. Binding spells are also potent on this day. Also
good for focusing and developing patience (something a lot of witches
don't have). Typically, I do not do spells on Saturdays unless it is to
get rid of unwanted energies or desires.
Sunday: The Sun; Truth in all matters. The sun is great for truth spells
and generating warmth in your heart. If you feel that you are frigid
inside and holding tons of resentment, use the Sun energy on Sundays to
shine through a cloudy heart.
