The 13 Moon 28-day calendar is the only calendar used by humans that takes into account the unity of planetary and galactic time. For this reason, the 13 Moon, 28-day calendar is often referred to as a synchronometer – a device for measuring synchronicity.
The 13-Moon 28-day measure is actually a fourth-dimensional harmonic function of galactic time. It is synchronized with the 260-day galactic spin or Tzolkin, the galactic synchronization standard, otherwise known as the 13:20 frequency. The 365-day solar cycle synchronizes with the 260-day galactic spin precisely every 52 years, to create the measure of the solar-galactic cycle.
It is the meshing of the 365-day solar and the 260-day galactic measures that makes the 13-Moon 28-day calendar a perfect synchronometer.
