If you buy a sundial as a gift, do not forget, please, to order an anniversary line. At the appointed day the shade on a sundial face will move along a specially calculated line. It may be a birthday, wedding day, or any other day you like.
According to a centuries-old tradition a motto or a dedication is advisable on a sundial face. You may choose a motto from the list or suggest your own one. Mottoes and anniversary lines etched on sundials in stock are free.
The duration of solar day is changeable within a year. Thus the difference between clock and sundial indications may be as high as 15 min depending on the season. You may easy convert solar time into mean time and vice versa using the equation of time table or graph. Usually I make it of brass, copper or stone.
