A sundial is a horological device that tells the time of day (referred to as civil time in modern usage) when direct sunlight shines by the apparent position of the Sun in the sky. In the narrowest sense of the word, it consists of a flat plate (the dial ) and a gnomon , which casts a shadow onto the dial.
Be as true to each other as this dial is to the sun. Begone about Thy business. Come along and grow old with me; the best is yet to be. [1] Hours fly, Flowers die. New days, New ways, Pass by. Love stays. [2] Hours fly, Flowers bloom and die. Old days, Old ways pass. Love stays. I only tell of sunny hours. I count only sunny hours.
Therefore, the analemmatic sundial is an ellipse, where the short axis is aligned north–south and the long axis is aligned east–west. The noon hour line points true North, whereas the hour lines for 6am and 6pm point due West and East, respectively; the ratio of the short to long axes equals the sine sin(Φ) of the local geographical ...

The Sunquest Sundial is a sundial designed by Richard L. Schmoyer in the 1950s. Adjustable for latitude and longitude, the Sunquest's gnomon automatically corrects for the equation of time allowing it to tell clock time. The Sunquest sundial utilizes a cast aluminum gnomon, the shape of which is related to the analemma. When turned to face the ...
A sundial schema uses a compass and a straight edge to firstly derive the essential angles for that latitude, then to use this to draw the hourlines on the dial plate. In modern terminology this would mean that graphical techniques were used to derive sin x {\displaystyle \sin x} and m tan y {\displaystyle m\tan y} and from it sin x ...
Animation showing equation of time and analemma path over one year.. The United States Naval Observatory states "the Equation of Time is the difference apparent solar time minus mean solar time", i.e. if the sun is ahead of the clock the sign is positive, and if the clock is ahead of the sun the sign is negative.
The instrument can be used with an accuracy of about 20 seconds by a skilled observer to determine the time of day, and the declination of the Sun and the other heavenly bodies. It is the world's largest stone sundial, and is known as the Samrat Yantra. [1] [2] The Jaipur Jantar Mantar is a UNESCO World Heritage Site. [3]
