No one knows for sure. But, it was the Mesopotamians. Most likely the Babylonians. They invented it in B.C. of course, but the accurate date is still unknown. The internet has so many answers, how do we know which one is really true?
The sundial is the oldest known device for the measurement of time and the most ancient of scientific instruments. It is based on the fact that the shadow of an object will move from one side of the object to the other as the sun "moves" from east to west during the day.
The first device for indicating the time of day was probably the gnomon. It consisted of a vertical stick or pillar; the length of the shadow it cast gave an indication of the time of day. It was "invented" in 5000-3500 BC.
Sundials were used in ancient Egypt and ancient Babylon, but there is no firm evidence the place where such things were first used.

The cost of a sundial can vary depending on its design, material, and size. On average, a simple sundial can cost anywhere from $20 to $100. More elaborate or custom-made sundials can cost several hundred dollars or more.

The first sundial is believed to have been made and used in Ancient Egypt around 1500 BC. Sundials were used to measure time by tracking the movement of the sun's shadow throughout the day.
The weight of a sundial can vary depending on its size and materials, but they are typically lightweight due to being made of materials like stone or metal. A small sundial made of lightweight materials may weigh only a few pounds, while larger or more ornate ones could be heavier.
