    Nice, as we can see the angles are not uniformly separated, can you please make video why is that so ? and based on what formula the angular gaps were designed. Thanks for sharing the amazing knowledge.

      Sure I will

      The angles will be uniformly separated if we replace the flat paper (scale) by a cone

      @@JayeshSarvaiya Each day the sun moves from east to west in a circle. But that circle is tilted. The amount of tilt is exactly equal to the latitude of the place of observation. When the angle of the gnomon is equal to the latitude, then when it points North, it points exactly to Dhruva Tara. In this position it becomes exactly parallel to the axis of rotation of the Earth.
      Now take a cone with semi angle equal to the latitude and place it with its tip coinciding with the bottom tip of the gnomon, and the open face (base) facing North. Now the circular rim of the base is always exactly parallel to the path of movement of the sun. Mark the angles on the rim. Since the sun moves uniformly, the angle markings are also equal in distance from each other.

    17 degree angle क्यों लिया गया. is it local time

      Jis place pe sundial use karte hei... wahaa ka Latitude lena hota hei... (its not local time... its local Latitude)
