Using a Clock or Watch: The most common method for determining time is using a clock or watch. Clocks can be analog or digital and typically display the hour, minute, and second.
Measuring Daylight: The amount of daylight can be used to determine the time of day. In the morning, the sun rises in the east and sets in the west as it moves across the sky.
Using the Stars: Astronomers have long used the stars to tell time. The stars move in a predictable pattern and the position of the stars in the night sky can be used to calculate the time.
Utilizing a Computer: Computer clocks are very accurate and can be set to a specific time zone. Using a computer to determine the time is often the most accurate option.
Using a Radio Signal: Radio signals broadcast from a source can be used to determine the time. Radio signals are usually sent from an atomic clock and are very accurate.
