TwitterSundial is an ancient way of telling time. Some people even say that solar time is more accurate than the clock, sundial is a important alternative to modern clock that gives time reading based on sunlight.
However, a sundial cannot give time accurately if it is not adjusted properly. The planetary society recommends three types of adjustment need to read the time of a sundial more correctly.
First of all, configuring the location of the sundial is very important that depends upon your position on earth that means you time zone. If you live in the western hemisphere, you should add 4 minutes for every degree of latitude. Alternatively, if you live on Eastern hemisphere, you should deduct 4 minutes for each degree.
It is very easy to know how much degree ahead or behind you are living from central time zone or GMT. Just calculate the difference between your local time and London time; then multiply the result with 15. This method allows you to play can convert solar time on your exact location at this time on your watch.

It is also important to set the summer time. In the summer you need to add one hour more in the reading of the sundial, to find the correct time.
The final configuration, you need to do is the most difficult and complex. With this readjestment, the clock was set to perform absolute uniformity, every hour a day without little distortion of a milisecond. However, this does not mean it is a easy task to do.
This meager adjustment that credits the sundial as most accurate clock in the world. In solar time, it is exactly 24 hours the earth rotates on its axis. But this time vary slightly except 4 days in a year. This time variation is very meager; can be 30 seconds more or less. It happens because, earth is bit tilted about 23.4 degree on its axis and the circular path the earth orbits around the sun is not standard circle rather than elliptical.
So, if you calculate this 30 seconds variation during a month, you will get about total 15 minutes per month. You may need a PHD in Mathematics to understand this, however if you are interested enough, you can visit wikipedia to have a gimps of the complexity working here. Fortunately, sophisticated commercial sundial this equation of time correction is done in a automated way.

If you have these three parameters, you can read the exact time on a sundial. Most people do not want to go through all this work, it is out of line subject, mostly people prefer to view a rough time. Regardless of how much detail you claim your time by sundial; it is an interesting addition to your yard or garden. They come in different styles and from different materials depending on what your aesthetic taste demands.
