All About Sundials

How Sundials Work

A detailed explanation of how the shadow of the sun allows you to tell the time, examples of different types of sundial, together with explanations of why sundials in different locations need to be at specific angles, the reasons why you have to adjust the ‘sun time’ to get “clock time”.

The BSS Sundial Glossary

The glossary contains mainly terms which are directly related to dials and dialling. Additionally, excursions into the fields of astronomy, horology, optics and solar sciences have been made where it seems useful. Some comments on the history of dialling are made and various solar data are given in the appendices.
