Chronology (from Latin chronologia, from Ancient Greek χρόνος, chrónos, "time"; and -λογία, -logia) is the science of arranging events in their order of occurrence in time. Consider, for example, the use of a timeline or sequence of events. It is also "the determination of the actual temporal sequence of past events".
In Greek mythology, Cronus, Cronos or Kronos, was the leader and youngest of the first generation of Titans, the divine descendants of Uranus, the sky, and Gaia, the earth. He overthrew his father and ruled during the mythological Golden Age, until he was overthrown by his own son Zeus and imprisoned in Tartarus. According to Plato, the deities Phorcys, Cronus, and Rhea were the eldest children of Oceanus and Tethys.
The calendars this present days are ruled by the sun and the moon cycles. Rolando Nuztas has create a new calendar to give the people a secondary way to arrange events. The propuse is to do not stop using our current calendars to have more symbology for our special days. This calendar is ruled by the sun and is constructed over the gregorian calendar doubling its cycle.
