So far we have known that there are many different kinds and models of sundials; there
are models Upright ( vertical Sundial ), horizontal ( Horizontal Sundial ) or even curved
( Equatorial Sundial ).
This time I tried to make a curved version which is a modification of various models of the
Equatorial Sundial/ equatorial dial/ equinoctial dial ; that exist all over the world.
So in addition to the instructions for the Hours/Times , there are also instructions for the months of January to December .
While the existence of Analemma which is similar to the number 8, to show the time correction.
This work of mine is a modification of some of the Sundials in:
- Ancient Bench Clock in several Mosques in Indonesia'
- Selangor Malaysia
- Bütgenbach, Belgium
Suitable for use in areas around the Equator; especially the latitude range of 23.5° North Latitude – 23.5° South Latitude.
I hope it's accurate and useful...
