A graha is not read in isolation but through the several tables that make up a Panchanga and a chart. It rules Saturday in the seven-day week, which in the Indian tradition as in the European one is named for the seven visible grahas in the order of the planetary hours. It holds 19 years of the Vimshottari dasha cycle, and it is lord of three of the twenty-seven nakshatras, Pushya, Anuradha and Uttara Bhadrapada, spaced nine apart so that the nine grahas cover the twenty-seven exactly three times over.
The Vimshottari dasha system divides a notional lifetime of 120 years among the nine grahas in a fixed order, Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn and Mercury, with fixed lengths that sum to exactly 120. Which period a person begins life in is determined by the nakshatra the Moon occupied at birth, and how far through that period, by how far through the nakshatra the Moon had travelled.
In the scheme of dignities it is exalted in Libra and in its fall in Aries, and dignity is what the classical rules for strength are built on, since a graha in its own sign or its exaltation is read as able to act and one in its fall as constrained.
Saturn's slow motion, roughly two and a half years to a sign, gives it the longest transit cycles in the system, and the passage of Saturn through the signs on either side of the natal Moon, a period of about seven and a half years known as sade sati, is among the most widely discussed transits in Indian practice. The atlas records that it is so discussed, and does not offer a reading of it.
