Archangel Raphael

[31 Sword Illusion]

I'm a little confused as to which day and planet the Archangel Raphael is associated with. On a number of sites, I've seen it said that he is associated with the day of Wednesday and the planet Mercury. In "The Grimoire of Armadel," it says that he is associated with the day of Sunday, and I've seen it said elsewhere that he is actually associated with the planet of the Sun. I'm planning on doing an evocation of him within the next few months, but it's important to me to know which planet and day he's truly known to be associated with. Can anyone please set me straight on this one? I'm a bit confused.
