Sidereal

• sidereal: determined by or from the stars

• sidereal time: a time-keeping system astronomers use to keep track of the direction to point their telescopes to view a given star in the night sky.

• twelve tribes of Israel

• Sidereal-based Astrology: Jyotish, Vedic (Hindu) Astrology, uses the astronomical Zodiac, i.e., the actual fixed-stars Zodiacal constellations observable in the "heathvens" outside, as opposed to the Western system which uses the Tropical Zodiac, starting on the first day of spring. Due to the precession of the equinoxes, they are out of kilter by about 24 degrees -- different schools have different measures for this delta, which in Vedic astrology is known as the ayanamsa.
  • (sidereal and standard (solar) time are nominally equal only twice a year, on the autumn equinox, when they are truly equal, and on the spring (vernal) equinox, when they are twelve hours apart; Joyce: Finnegans Wake is assumed to take place on or around the latter) .. sidereal time: time measured relative to the fixed stars (used primarily in astronomy; a sidereal day is about 4 minutes shorter than the 24-hour standard solar day)
