Jewish Tools for Saturn's Return: The Return

The Sages taught: One who sees the sun in the beginning of its cycle, the moon in its might, the planets in their orbit, or the signs of the zodiac aligned in their order recites: Blessed…Author of creation. The Gemara asks: And when is it that the sun is at the beginning of its cycle? Abaye said: Every twenty-eight years when the cycle is complete and returns to its genesis, and the Nisan, vernal, equinox, when the spring days and nights are of equal length, falls within the constellation of Saturn on the night of the third and eve of the fourth day of the week, as then their arrangement returns to be as it was when the constellations were first placed in the heavens.

The great cycle of the sun is 28 years, and therein are seven small cycles each of four years. The number of days of the solar year is 365 and a quarter of a day. The seasons of the solar year are four, each season (consisting of) 91 days 7½ hours. The beginnings of the cycles of the seasons are the 4th, 2nd, 7th, 5th, 3rd, 1st, and 6th (days). Between each cycle there are 5 days and 6 (hours).

The first cycle took place at the beginning of the hour of Saturn, (and the names of the Planets of the hours are) Saturn, Jupiter, Mars, the Sun, Venus, Mercury, and the Moon. The second cycle occurred in the hour (of the Planet) which is in front of it, (i.e.) at the beginning of the hour of Jupiter. The third cycle occurred at the beginning of the hour of Mars. The fourth cycle entered at the beginning of the hour of the Sun. The fifth cycle entered at the beginning of the hour of Venus. The sixth cycle entered at the beginning of the hour of Mercury. The seventh cycle entered at the beginning (of the hour) of the Moon. (At) the end of seven hours, at the end of seven cycles, at the end of 35 days of the great cycle of 28 years, the Teḳuphah cycle returns (i.e. begins again) at the beginning of the fourth day in the hour of Saturn in the hour when it was created.
