Very accurate too.
Morning Sunshine:
I was just thinking about sundials the other day. and i have a question
I know that the time of year makes a difference for where the sun is in the sky. How do sundials work all year round?

Good question. You anticipated Part 4: The Equation of Time and Analemma. It will show how the sundials are actually a little off by the change in sun altitude through the seasons. This will fill in how to make sundial better match 'clock time' and also how a sundial can be used as a calendar to give month and day!

In modern times the sundial is used as a rallying point to give a sense of "community" such as the recently constructed Perranporth Sundial in Cornwall.
