Is associated with the Sun and zodiac sign of Leo. I add Cancer and Aries to this because they are also associated with the Sun.
The elemental correspondence is Fire.
In my opinion Sunday is the most diverse day in terms of its spell correspondences. Spells for success, money/prosperity, healing, protection, insight, fame/power, attraction and empowerment are just a few of the spells that can be amplified if performed on a Sunday.
Gods/Goddesses: Helios, Brigid. Brigid is the Goddess of Fire and the Hearth and is celebrated on Imbolc, which is known as the “Festival of Lights”. By invoking her on Sundays you can tap into her powers of illumination and maternal energy.
Angel: Michael. Archangel Michael is the ultimate warrior. He can be petitioned to help aid your cause or to destroy an enemy. If this is an angel you work with often, Sunday would be an auspicious day for honoring him and offering him gifts of thanks.
Taking its name from our closet star, the Sun, Sunday is the best day of the week to work magic involving fathers and other authority figures such as your boss. It is also a good day to work on questions regarding leadership, money, prosperity, and power.
