Sidereal day

Definition and stakes

Edmund Beckett,  Encyclopædia Britannica, Ninth Edition (1878)

“ A sidereal day is the interval between two successive transits over the meridian of a place by that imagin ary point in the heavens called T, the first point of Aries, at the intersection of the equator and the ecliptic ; and there is one more sidereal day than there are solar days in a year, since the earth has to turn more than once round iii space before the sun can coma a second time to the meridian, on account of the earth s own motion in its orbit during the day. ”

“ EVERY nation in the world has its New Year’s Day. A year is the time of the apparent revolution of the sun through the ecliptic; and a sidereal year is the time in which the sun departing from any fixed star returns to the same. The Hindu’s astronomical year is sidereal. He calls it Samvatsaradi, the first day of the year or the Vishu-chaitravishu, the equinoctical point of Aries, into which the sun enters at the vernal equinox. ”
