Assume it's two o'clock in the afternoon. To establish the north-south line, draw an imaginary line between the hour hand and twelve o'clock. Because the sun rises in the east and sets in the west, you can identify which direction is north and which way is south by looking at the sky. If you live in the southern hemisphere, the situation will be reversed. The north-south line will now be based on four o'clock instead of twelve o'clock. In the northern hemisphere, if you were to look up at the sky right now, you would see that the sun is just above the horizon in the east. This means that it is still daytime and you can continue to follow the instructions below to find out which way is south. The process for telling which way is north is exactly the same as telling which way is south. All you need to remember is that in the northern hemisphere, the sun goes down in the west and rises in the east. So draw an imaginary line from three o'clock to nine o'clock to determine the north-south line. This method isn't very accurate unless you live in a region with a relatively small land mass, like North America or Europe. For example, using this method to find south in Africa would lead you to believe that it is still day when it is night time. There are more precise methods for finding south in areas such as Africa.
