Use to cast spells aimed at bringing about quick changes of all kinds, but it will work best when the Moon is in a mutable sign. If it is in a cardinal or fixed sign the work could fail and result in frustration or confession.

To change bad luck to good, use a Mercury hour on a day of Venus. This is not for the chronically greedy, or the malcontent as if they are actually enjoying their due share of good luck but simply dont take advantage of the benefits or make good use of them the opposite, in order to teach a lesson.

Remember, Venus leads toward Natural Order and wants to right things which are wrong or inequitable and Mercury maneuvers the change. This is also a good time for healing works, when the Moon is in Taurus, Virgo or Capricorn.

Use a Mercury hour to seek forgiveness, and to make amends, when a strong change in attitudes is desired, or to cause people who have been feuding to make up and become friends. Also to cause troublesome-in-laws or relatives to altar their ways, or become reasonable. When the Moon is in conjuction with Uranus the Mercury hour is used to completely upset or wreck and establishment or trend.
