A garden sundial is a wonderful choice to place in your yard because they will add an element of quaint charm to your decorating. However, sundials are not just decorative. They are an ancient method of keeping time, which you can still use today to determine the time.
Simply reading your sundial will give you a fairly close approximation of the actual clock time. However, if you want a more accurate reading, you’ll have to make a few adjustments.
First, you will have to alter your reading to compensate for your location within your time zone. Sundials on the eastern edge of the time zone will be about thirty minutes fast, while western edge sundials will be thirty minutes slow.

The general rules you should follow when adjusting your sundial reading as follows.
1. For every degree of longitude east of the center of the time zone you are, subtract four minutes from the time you read on your sundial.
2. For every degree of longitude west of the center of the time zone you are add four minutes to the time you read on your sundial.
3. Don’t forget about daylight savings time! During the summer, you need to add one hour to the time you read on your sundial in order to find the actual clock time.
Follow these simple rules, and your garden sundial will transform from a simple backyard decoration into an attractive timepiece!
