What Is Noon?

The English language is a tiny imprecise as soon as it involves the word “noon”. It can intend 2 different things:

Meridians and the Sun

A meridian is an imaginary line running from the North Pole to the South Pole along the Earth"s surchallenge. It connects all places that share the very same longitude, interpretation that they are specifically north or southern of each other. The line running from one pole to the various other using your place is your regional meridian.

Solar noon happens at your area as soon as the Earth"s rotation brings your neighborhood meridian to the side of the earth that deals with the Sun. From your perspective, the Sun, after having steadily obtained altitude since sunincrease, currently reaches the optimal of the arch that its journey describes in the skies eextremely day. At this moment, it shows up due south, due north, or in the zenith position specifically above you, depending upon your latitude and the moment of year.

Due to the fact that solar time relies on the longitude, solar noon occurs at exactly the very same minute in all places that share your local meridian.

When Is Solar Noon?

In most locations on Planet, solar noon does not happen at 12 o"clock. The Earth"s rotation progressively shifts the meridian suffering solar noon from eastern to west. In various other words, solar noon happens a small earlier in places simply eastern of you and also a little later on in areas west of you.

Where"s Sun right now?

Since our clocks are set according to time areas, civil time alters abruptly as you move from one time zone to one more, normally in 1-hour increments. While this undeniably renders life easier for us, it does not reflect the even activity of the Earth"s rotation and also the steady geographical progression of local solar time.

This means that clocks in the eastern component of each time zone display an earlier time at solar noon than clocks close to its western border. Even if time areas were provided the means they were when envisioned—wbelow local time is based upon the solar time in the zone"s facility, via the moment zone extfinishing 7.5 degrees of longitude to the west and to the east of the facility line—solar noon would certainly occur at 11:30 (11:30 am) at the eastern time zone border and also at 12:30 (12:30 pm) at the western border.

Latest Solar Noon in China

In actual life, this distinction is also larger because time areas seldom follow this ideal. Their borders are regularly grossly distorted by political or geographical determinants. For example, China spans more than 60 levels of longitude but the nation follows a single time zone. This indicates that solar noon in western locations occurs later than 15:00 (3:00 pm) during some components of the year, later on than everywhere else on Earth.

In many countries, Daylight Saving Time (DST) additionally boosts the discrepancy between civil and also solar time.

Elastic Solar Time

Of course, if you occur to live in a location whose solar time is offered as the basis for civil time in your time zone, solar noon will certainly happen at or about 12 o"clock for you. But even that is just true in the time of some parts of the year. The Earth"s rotation and also its movements in relation to the Sun are not quite constant, so the length of a solar day, which is the moment expectancy from one solar noon to the next, varies during the course of a year. This phenomenon is referred to as the equation of time.

For instance, about the December solstice, solar noons are a bit farther acomponent, so the Sun crosses the neighborhood meridian a tiny later on eincredibly day. Throughout other parts of the year, for instance in the time adhering to the June solstice, solar noon happens a tiny earlier each day and also solar days are a little shorter.

Solar Noon at the Poles

All meridians converge at the North Pole and also the South Pole. So, unprefer any kind of various other area on Planet, the poles do not have actually a longitude. By expansion, tright here is no solar noon because tright here is no meridian the Sun have the right to cross.

In practice, the Sun does not go up and dvery own on a daily basis prefer almost everywhere else on Earth. Rather, its altitude in the sky constantly boosts during the winter and spring and decreases in the time of the summer and also loss (fall), creating 6 months of polar night, followed by 6 months of midnight Sun. At the North Pole, for instance, the Sun reaches its lowest altitude at the December solstice, which marks the start of winter tright here, and its highest possible position at the June solstice, as soon as summer starts.

Where Does the Word Noon Come From?

Its origin lies in the Latin word none, referring to the 9th hour after daybreak. Originally, it was offered to signify the timing of a everyday prayer or meal at 15:00 (3:00 pm), nine hrs after 06:00 (6:00 am). In the 12th century, the prayer and also meal were shifted to 12:00 (12:00 pm), while the term none stayed the exact same, inspiring the usage and timing of today"s noon.
