   It is the day on which the branch of the day matches that of the month, and it opens the cycle. In ancient times the emperor devoted it to prayers for the harvest. Today it is chosen for getting engaged and asking for someone's hand, for starting a job or taking on a new role, for doing business and for visiting friends: in the old calendars “visiting friends” meant arranging a marriage, which was business in every sense. It is good for setting out, for starting a treatment, a school or a course, and for building. It is not good for demolishing or for innovating, which are another matter.

   Favorable for

   • Medical treatment
   • Marriage proposal, engagement
   • Starting a job or a new role
   • Launching a business, a project, a negotiation
   • Enrolling in a course of study
   • Setting out on a trip for pleasure or business
   • Rebuilding work

   Unfavorable for

   • Wedding
   • Demolition
   • Innovation

   The 協紀辨方書 Xiéjì Biànfāng Shū (“Book for Harmonizing the Times and Distinguishing the Directions”) holds it good or bad according to the stars that accompany it: it is the “lord of the month” and gives strength to whatever it meets.
