True noon

Noon (also midday or noon time) is 12 o'clock in the daytime, as opposed to midnight. The term 12 p.m. (for post meridiem, and also written as 12 pm or similar variations thereof) is sometimes used for noon.

Solar noon is the time when the Sun appears to contact the local celestial meridian. This is when the Sun apparently reaches its highest point in the sky, at 12 noon apparent solar time. The local or clock time of solar noon depends on the longitude and date.

In many cultures in the Northern Hemisphere, noon had ancient geographic associations with the direction "south" (as did midnight with "north" in some cultures). Remnants of the noon = south association are preserved in the words for noon in French (Midi) and Italian (Mezzogiorno), both of which also refer to the southern parts of the respective countries. Modern Polish, Belarusian, Ukrainian, and Serbian go a step farther, with the words for noon (południe, поўдзень, південь, пoднe – literally "half-day") also meaning "south" and the words for "midnight" (północ, поўнач, північ, пoнoħ – literally "half-night", as with English mid(dle) meaning "half") also meaning "north".
