Mercury

[Lyra]

Currently the next Mercury square is in September. I wonder is it possible to start a Mercury square on a date not set by the Calendar or a number of vibrations to be repeated over a period of 40 or more days to empower the left side of the brain through Mercury. Is it possible to start on a date not indicated by the astrological calendar? Thanks for the answers.

Is possible to start a magic square when the planet is in a sign other than its ruling one, but since it is not in its ruling or exalted sign, it will have less power and be less effective.

For example, it is perfectly fine to start a solar square in Taurus or Scorpio.

Never start a square when the planet is in a sign of detriment or fall.
