But what if you don't have all day and you want to find North/South now?
You will need:
1. A wrist watch.
2. The Sun.
Step 1: Aline Your Watch
Step 2: Imagine Lines
Before noon you measure the angle created between the hour hand to the 12 O’clock, in a clockwise direction. After noon you measure the angle between the hour hand and 12 O’clock in an anticlockwise direction.
We will use the example of 7 O’clock:
At 7 am, we make an angle from the hour hand to 12 in a clockwise direction (7,8,9,10,11,12). This gives us a 150 degree angle, so South is at 75 degrees, half way between 9 and 10.
At 7 pm, we make an angle from the hour hand to 12 in a anticlockwise direction (7,6,5,4,3,2,1,12). This gives us a 210 degree angle, so South is at 105 degrees, half way between 3 and 4.
I hope this clears it up for you, but the best way to understand this is to go outside and try it out for yourself at differenttimes of the day.
