Appropriate times for magic
Both the moon and the day of the week have meanings. Don't worry about trying to make them both match up, just pick one and work with it.
New Moon (1 day before and 1 day after): rituals about beginnings (blessing a new job, a new home, or a new born baby), love/romance (creating a new relationship), health (especially improving, not healing).
Waxing (growing moon, lasts for about 13 days): inspiration (like for reports or making techs), love/friendship (growing closer to someone you're already close to), prosperity, happiness.
Full Moon (1 day before and 1 day after): healing, predictions, granting wishes, money, strength.
Waxing (shrinking moon, lasts for about 13 days): breaking curses, anything with negative powers (making them or getting rid of them, getting rid of addictions, and anything about "undoing" stuff
Sunday: healing, comfort
Monday: beginnings, work, family/close friends
Tuesday: courage, strength, lust
