Noon is at 12 o'clock. But what about solar noon? What and when is it and what does your local longitude have to do with it? Is it at the same time every day?
A tall pole vertically fixed in the ground casts a shadow on any sunny day. At one moment during the day, the shadow will point exactly north or south (or disappear when and if the Sun moves directly overhead). That instant is called local apparent noon, or 12:00 local apparent time. About 24 hours later the shadow will again point north ...
Our website allows you to easily and quickly check the local solar time of your current location for maximum accuracy. Discover the precise solar time for your location now, thanks to heuresolaire.com - the easiest and most reliable way to stay on solar time!
Our latitude and longitude page will help you to find the input data you need for our unique Solar Noon Calculator. The time of solar noon depends on the Equation of Time and on the difference in longitude between your location and the standard meridian of the time zone you are in.

Twelve noon local solar time (LST) is defined as when the sun is highest in the sky. Local time (LT) usually varies from LST because of the eccentricity of the Earth's orbit, and because of human adjustments such as time zones and daylight saving.
The Local Standard Time Meridian (LSTM) is a reference meridian used for a particular time zone and is similar to the Prime Meridian, which is used for Greenwich Mean Time. The LSTM is illustrated below. The (LSTM) is calculated according to the equation: LSTM=150∆TUTC where ΔTUTC is the difference of the Local Time (LT) from Universal Coordinated ...
The equation of time (EoT) (in minutes) is an empirical equation that corrects for the eccentricity of the Earth's orbit and the Earth's axial tilt. An approximation 2accurate to within ½ minute is: EoT=9.87sin2B-7.53cosB-1.5sinB where B=360365(d−81) in degrees and dis the number of days since the start of the year. The time correction EoT is plo...
The net Time Correction Factor (in minutes) accounts for the variation of the Local Solar Time (LST) within a given time zone due to the longitude variations within the time zone and also incorporates the EoT above. TC=4(Longitude−LSTM)+EoT The factor of 4 minutes comes from the fact that the Earth rotates 1° every 4 minutes.
The Hour Angle converts the local solar time (LST) into the number of degrees which the sun moves across the sky. By definition, the Hour Angle is 0° at solar noon. Since the Earth rotates 15° per hour, each hour away from solar noon corresponds to an angular motion of the sun in the sky of 15°. In the morning the hour angle is negative, in the aft...
The conversion of LT to LST is complicated by the world’s time zones and there is not a simple conversion from a location to its time zone. The calculator below uses Google to determine the time zone from its location. It will accept any description such as an address, city name, airport code and then show its location on a map. It also determines ...
