# Determining the approximate time of the day by the shadow of the pole, primitive sundials, determining the sides of the horizon by the clock on which the time is set by the Sun.

The method of determining the direction to the north in the shadow of the pole can also be used to determine the approximate time of the day. Determining the time of day will be very important for making an appointment. Carrying out the planned concerted action by individuals or groups. Determining the remaining day before dark and so on.

## Determining the approximate time of the day by the shadow of the pole, primitive sundials, determining the sides of the horizon by the clock on which the time is set by the Sun.

Determining the approximate time of the day by the shadow of the pole is as follows:

1. Move the pole to the point of intersection of the east-west and north-south lines and place it vertically on the ground. In any place of the globe, the western part of the line corresponds to 6.00 hours, and the eastern part – 18.00.

2. Now the North-South line becomes a midday line. The shadow of the pole is like a clockwise hand on a sundial. With it, you can determine the time. Depending on your location and time of year, the shadow can move either clockwise or against it. But this does not interfere with the determination of time.

3. A sundial is not a watch in the usual sense. The duration of the hour during the year is not the same for them. However, it is generally accepted that 6.00 always corresponds to sunrise, and 18.00 to sunset.

However, a sundial is quite suitable for determining the time in the absence of a real watch or in order to correctly set or check your wristwatch. The designation of 12.00 on a sundial will always really correspond to noon. However, other clockwise readings compared to normal time are slightly different depending on location and date..

## Definitions of the sides of the horizon by the clock on which the time is set by the Sun.

The method of determining the sides of the horizontal clock can give erroneous readings. Especially in low latitudes, and this can lead to whirling. To avoid this, set your watch in the sun, and then determine the sides of the horizon. With this method, the 10-minute wait necessary to determine the sides of the horizon to the movement of the shadow is eliminated..

You can get as many indicators during this time as you need to avoid circling. After about an hour in one direction, check the sundial. Rearrange arrows if necessary.

The definition of the sides of the horizon in such a modified way, after setting the time of the watch according to the sun, will correspond to the determination of the direction to the north from the shadow of the pole. The degree of accuracy of both methods is the same..
