'''Noon''' (also '''midday''') is the hour of 12:00 pm (1200) in an observer's local time zone, or more loosely, a time near the middle of the day when workers in many countries take a meal break. The scientific term '''[[#Solar noon|solar noon]]''' describes the moment when the sun crosses the meridian in [[apparent solar time]].
The [[antonym|opposite]] of noon is [[midnight]].
==Etymology==
The word "noon" is derived from Latin '''nona hora''', the ninth hour of the day. The Roman and Western European medieval monastic day began at 6:00 am (0600) by modern timekeeping, so the ninth hour began at what is now 2:00 pm (1400). In English, the meaning of the word shifted to ''midday'' by the year 1100 CE.<ref>[http://www.etymonline.com/index.php?term=noon Online Etymology Dictionary<!-- Bot generated title -->]</ref>
==Solar noon==
Solar noon is the moment when the sun appears the highest in the [[sky]] (nearest [[zenith]]), compared to its positions during the rest of the day. It occurs when the Sun is [[transit (astronomy)|transit]]ting the [[astronomy|celestial]] [[meridian (astronomy)|meridian]]. This is also the origin of the terms ''[[12-hour clock|ante meridiem]]'' and ''[[12-hour clock|post meridiem]]'' as noted above. The Sun is directly overhead at solar noon at the [[equator]] on the [[equinox]]es; at [[Tropic of Cancer]] ([[latitude]] 23° 26′ 22″ N) on the June [[solstice]]; and at [[Tropic of Capricorn]] (23° 26′ 22″ S) on the December solstice. Due to the effects of the use of [[standard time]], [[daylight saving time]], and the [[equation of time]], clock noon and solar noon rarely coincide.
