What are the benefits of a sundial?
A sundial is no good unless the sun is shining, and a shadow is cast.
Will a sundial work on a cloudy day?
A sundial relies on the position of the sun to cast a shadow, so on a cloudy day when the sun is obscured, a sundial would not be able to accurately tell time.
What are the limitations of the sundial?
A sundial is no good unless the sun is shining strongly enough to cast a shadow.
What is the pin of a sundial whose shadow points to the hour called?
The pin of a sundial where the shadow falls is called the gnomon. It is typically a thin, straight rod that extends vertically from the sundial's base. The shadow cast by the gnomon is used to indicate the time of day on the sundial's face.
What is a clock that works by the suns shadows?
A sundial is a type of clock that works by using the shadows cast by the sun. The position of the shadow tells the time based on the sundial's design.

When is sundial not working?
A sundial is not accurate when it is cloudy, rainy, or at night when there is no direct sunlight to cast a shadow. Additionally, if the sundial is not properly calibrated for its location or if it is moved, it may not accurately tell time.
Why portable sundial need a compass?
A portable sundial needs a compass to ensure it is correctly aligned with true north. This alignment allows the sundial to accurately cast a shadow based on the position of the sun, which changes throughout the day and across seasons. Without a compass, the sundial could provide incorrect time readings, as the shadow would not correspond accurately to the sun's position in the sky. Thus, the compass is essential for precise timekeeping with a sundial.
Who created sundial?
the Greeks
Did Ptolemy developed a system to determine true north?
Yes, Ptolemy developed a method to determine true north by using a sundial. By observing the shadow cast by the sundial at different times of the day, one could align the sundial's gnomon (the part that casts the shadow) with true north.
