A sundial is a device that measures time by the position of the Sun. In common designs such as the horizontal sundial, the sun casts a shadow from its style (a thin rod or a sharp, straight edge) ...

The seasonal correction is known as the "equation of time" and must obviously be taken into account if we want our sundial to be exact to the minute. ... If you believe the sundial outside, without accounting for the equation of time. you will already be late for the 11:00 session as soon as you step out the door.

"Fast" means that, if you are on the standard meridian for your time zone, the sun will be directly overhead ("sun noon") not at 12:00:00 by your watch, but a few minutes earlier. When you are setting up your horizontal sundial, you want to know the time the sun is directly overhead.

Early in November, sundial time is about 16 minutes ahead of mean clock time, which means that the mornings get half an hour more daylight than the afternoons. In February, sundial time can be 14 minutes behind mean clock time, which means that the afternoons get a longer period of daylight than the mornings.

As an understanding of the solar orbit facilitates the creation of good calendars, it also enables the better construction of sundials. To the philosophers who mapped the "sun's" orbit and advanced the use of astronomy to measure time, the third century sundial architects owe a great debt of gratitude.

(Up to the second half of the 19th century, local time and sundial time were generally the same, and each city kept its own local time, as is still the case in Saudi Arabia. In the US standard time was introduced by the railroads, to help set up uniform timetables across the nation.)

sundial is a simple instrument for reading time during daylight hours from the position of the Sun. However , comparison of sundial time, also called apparent time, with standard time usually shows a considerable difference, and the difference increases and decreases during the year.
