Solar time

Solar Time is like telling time using the Sun instead of a clock or watch. When we look up at the sky on a sunny day, we can see that the Sun moves across the sky from east to west. The time of day that we see the Sun in the highest point in the sky is called noon.

However, the way that we measure time using a clock or watch is different from this solar time. A clock measures time based on the length of a day, which is an average of the time it takes for the Earth to rotate once on its axis. This can sometimes be different than the amount of time it takes for the Sun to appear at noon every day because the Earth's orbit is not perfectly circular and its axis is tilted.

To make up for this difference, some places use what is called a sundial, which uses the Sun's position in the sky to tell time. The position of the shadow cast by the Sun changes throughout the day, and a sundial has markings to show the time based on where the shadow falls.

So, solar time is basically telling time based on where the Sun is in the sky, and can be different from the time on a clock or watch because of the Earth's movements. It can be measured using a sundial or by carefully observing the Sun's position in the sky.
