The conception of pre-established geological history that is worked out on the base of deciphering the «stone chronicle» of the Earth crust permits to create the universal geochronological multi-level calendar, that embraces all the history of our planet. This calendar is ontologically correct. It means that calendar can be effectively used for retrospective and perspective prognosis of the main events of geological history. Geochronologic calendar is based on several chronometric galactic and metagalactic cycles, that control the life of our planet. Central place takes the anomalistic galactic year (AGY) ? period of the Solar system movement around the Centre of the Milky Way Galaxy. As it was determined by astronomic and geological date AGY is equal to 176 million years. The second important chronometrical galactic cycle is the periodical movement of the Solar system perpendicularly to the galactic flat. Its period is equal to ½ AGY (88 mil years). During one such period Solar system intersects twice the galactic radio-active belt so the galactic year is divided into four galactic seasons. Duration of such a season is equal ¼ AGY (44 mil years). The calendar geologic period is equal to one galactic season. One calendar geological period is equal two one galactic season. Each geologic period is divided in two epochs (22 million years): one epoch of tectogenesis, when the Earth moves in galactic radioactive belt, and tectonically relatively passive epoch. Each calendar geologic epoch is divided two calendar geological ages (11 million years), each calendar age is divided in two hemi-ages (5,5 mil year). Such binary division can be continued up to calendar hemi-quant (343 750 years). It can be proposed the technique of determination of global temporal markers to fix in geological sections the calendars boundaries of different ranks up to boundaries of half ? hemi-quants.
