Points of Direction: People rarely know that if the Sun is not shining they can depict the points of direction by using a pocket watch. If the hour needle of a watch is oriented to the Sun then it will be South between the number 12 onto the watch and North in its exact center. It becomes clear that when moving from the east to South the Sun passes through 150 degree. The hour needle of the clock covers 360 degrees from 6 am to 6 pm. Since the movement of one hour made by the Sun is equal to half an hour movement of a clock if the hour needle is turned to the Sun then the hour needle and the intermediate line of 12 O’clock will pass through the center of needles South ward, and other directions will he shown by it.
Length of the Day and the Night: Double the number of hours
on which the Sun has set. This will show the length of day. Double the number
of hours on which the Sun has risen. It will show the length of night. Suppose
Sun sets at 6 O’clock the length of day will be 12 hours. If the Sun rises at 7
O’clock the length of night will be 14 hours.
Length of Day in Foreign Countries: At Hamburg in Germany
the longest day is of 17 hours and the shortest of 7 hours. In stock holm the
longest day is of 18 hours and the shortest on is 5-5 hours. At Saint
Petersburg, the capital of Russia, the longest day is of 19 hours and the
shortest one is of 5 hours. In Norway, the longest day is of one and a half
month as the Sun does not descend down the horizon. Rather it moves towards
North along the horizon.
