The sun temple at Konark in Odisha is carved in the shape of a chariot. It is drawn by seven horses, representing the days of the week and has 12 stone wheels, representing the months of the year. Each wheel has 8 spokes representing 3 hour intervals, in all 24 hours. The spokes of the wheel form the shape of a sundial. The exact time of the day can be calculated seeing the shadow cast by the wheels.
