where did the term high noon come from
Noon Solar noon (informally high noon)[3] is the moment when the Sun contacts the observer's meridian, reaching its highest position above the horizon on that day ("Sun transit time"). This is also the origin of the terms ante meridiem (a.m.) and post meridiem (p.m.), as noted below. The Sun is directly overhead at solar noon at the Equator on the equinoxes, at the Tropic of Cancer (latitude 23°26′13.0″ N) on the June solstice and at the Tropic of Capricorn (23°26′13.0″ S) on the December solstice. In the Northern Hemisphere, north of the Tropic of Cancer, the Sun is due south of the observer at solar noon; in the Southern Hemisphere, south of the Tropic of Capricorn, it is due north.
Eight-hour day Robert Owen had raised the demand for a ten-hour day in 1810, and instituted it in his socialist enterprise at New Lanark. By 1817 he had formulated the goal of the eight-hour day and coined the slogan: "Eight hours' labour, Eight hours' recreation, Eight hours' rest". Women and children in England were granted the ten-hour day in 1847. French workers won the 12-hour day after the February Revolution of 1848.[3] A shorter working day and improved working conditions were part of the general protests and agitation for Chartist reforms and the early organisation of trade unions.
