We don’t know who first discovered a way to measure time. It was probably the Hindus, the Greeks, or the Egyptians. We do know, however, that more than 7, 000 years ago the Hindus looked at the sky and measured time by looking at the position of the stars and the sun.

The Egyptians used the water clock. This measured the time it took for a certain amount of water to pass from one place to another. The Egyptians were also the first people to make a calendar of 365 days. The earliest known water clock was found in the tomb of the Egyptian pharaoh(法老)Amenhotep I, who was buried around 1, 500 BC.

The hourglass(时漏) was probably invented in the 3rd century BC. No one knows for sure. This was similar in a way to the water clock. Time was measured by the amount of sand that moved from one container to another. We still use this kind of clock today in the form of an egg timer(煮鸡蛋的定时器). This measures time in three minute periods.

The first clock of any kinds to be used in China were brought there by European explorers. And it was in Europe that the first mechanical clock was invented. The word “clock” comes from the Latin “clocca” which means bell, and it was first used in the 14thcentury.
