Description

The sidereal month

A sidereal orbit of the moon through the zodiac takes 27.32 days in relation to the fixed stars. In the 29th octave, this corresponds to the tone of these tuning forks at 227.43 Hz. The octave analog color is yellow.


The difference between the sidereal and the synodic month

  • Sidereal: periods in relation to the fixed stars. Assume that the sun and moon are in front of a particular fixed star at new moon in the zodiac. A sidereal month is completed when the moon is again in front of this fixed star after a complete orbit.
  • Synodic: Periods in relation to the sun. As the sun has moved about one sign of the zodiac during the sidereal month, it takes a further 2 1/4 days to complete a synodic month at new moon, i.e. a total of 29.53 days.
