The Shepherd Gate Clock was linked to the main ' motor clock' inside the Royal Observatory, which from 1852 to 1893 was the central clock that determined the whole British time system.īy using telegraph wires, the time determined by this highly accurate Observatory clock could be shared across the country.
If you want to confuse your friends, you can own your very own replica version.īut this clock has another secret. That means that the hour hand goes round only once in every 24 hours.Īt 12 noon, instead of pointing straight up, the hour hand points straight down at XII. Instead of the usual numbers 1-12 on its clock face, it has 24 Roman numerals.
In literal terms, it refers to a time specifically after noon.This is the Shepherd Gate Clock, which since 1852 has been installed outside the gates of the Royal Observatory Greenwich. In human life, it occupies roughly the latter half of the standard working and school day. Afternoon is the time when the Sun is descending from its zenith in the sky to somewhat before its terminus in the westerly horizon. Afternoon ends and evening starts at roughly 5pm or 6pm or maybe just before sunset. (This is equally true for “evening” and “night”.) However afternoon is often taken to start directly after noon (12:00pm). There is no exact definition of the time when afternoon ends and evening starts. The local or clock time of solar noon depends on the longitude and date.Īfternoon is the time of day from noon or lunchtime until evening. This is when the Sun apparently reaches its highest point in the sky, at 12 noon apparent solar time and can be observed using a sundial. Solar noon is the time when the Sun appears to contact the local celestial meridian. Noon and midday may not be on the same time. It is synonymous of midday, which is of different concept and points to the middle of the day-light period. Noon (or noon time) is 12 o’clock in the daytime, as opposed to midnight.
