Can you tell the time by looking at the position of the sun in the sky?

Yes, you can tell time by looking at the position of the sun in the sky. This method is known as sundial or solar time. Before the invention of modern clocks, sundials were commonly used to measure time.

The position of the sun changes throughout the day, and by measuring the length and direction of the shadow cast by a sundial, you can determine the time. The basic principle is that the sun moves from east to west, so the shadow cast by a stationary object will move in the opposite direction.

However, there are some limitations to this method. The position of the sun varies with latitude, and so does the time zone. Also, the position of the sun is affected by seasonal changes, and so the length of the day and the time of sunrise and sunset can vary greatly throughout the year.
