• The sundial is accurate in the center of each time zone. Consult the column marked "Zone Corr" in the table on the back of the sundial to find the time zone correction for the city nearest you. If the city is in the eastern portion of your time zone, the table will show a minus correction; if it is in the western portion, a plus correction. Add or subtract the number shown for your city to or from the time obtained by applying the seasonal correction above.
  • Note: You may want to purchase a small, inexpensive compass at your local variety store and imbed it in the bottom section of the sundial next to the north arrow. You can do this by cutting a hole just large enough for the compass to fit. Then you'll be able to carry your sundial with you and set it to tell time accurately whereever you are.
