But it is close enough that it works very well. So, now although in theory everyone has "noon" defined as the time when the sun is at it's highest in their area, it is actually derived from the Mean-Time an measured in Greenwich. Why not choose the one set by the boffins at Greenwich, especially as they have now worked out some clever ways to average out differences in the measured "highest-point of the sun". It really helps if it is easy to convert from one to the other, so the whole world needs to agree that one is the "master" version of "noon" and all others are a fixed number of hours away. Where countries are too big East-West they really need to divide themselves up into sections and each section sets its own noon.

It makes sense for this to be a place full of people that can measure such things and judge the right way to keep it sane - such as the country's main centre for astronomy (in the UK that was traditionally Greenwich). Noon = the time when the sun is as high as it's going to get today (= mid-day!)Īll other times in the day are derived from that.Īs it's best for everyone in the same country to share the same "time" (within reason) small countries should pick one place and use that to define "noon" for the whole country.
Why does no one understand time these days!
