New moon

You can do it on the 23rd or you can wait until the 30th when the moon is closer to the dark.

do i need an alter? What do u put on the alter other than what the spell told me to put on?

Your page you see here can include the moon phase by going to your bio, and edit, then scroll down to make choices of what you want to see. Hope this helped. Blessings...

Friday the 23rd would be fine.

But the planetary hours are a bit more complicated than that. The hours of Venus on the 23rd would be the 1st, 8th, 15th, and 22nd hours after sunrise on the 23rd. And of course the hour of sunrise would depend on where you live.

If the spell calls for you to have an altar then it would be a good idea to have one. Unless you have some particular beliefs associated with altars then nothing would be necessary other than the items called for in the spell.
