While holding it horizontally, aim the hour hand of your analog watch at the Sun.

Halfway between this, and twelve o'clock on the dial, will be due South, in the Northern Hemisphere.

In the Southern Hemisphere, it would be due North.

This works if your watch is on something close to sun time.

You can set your watch to sun time by setting it to noon when the sun reaches its zenith.

Jeff SmithDigital? I'm shocked. I figured you'd wear a sun dial if anything.

First try, someone else can check:

Convert the time to 24 hour format. 8:05 pm --> 20:05

Convert the minutes to a decimal part of an hour. 20:05 --> 20.0833

Subtract 12. 20.0833 --> 8.0833 (negative means left instead of right later.)

Multiply by 30. --> 242.4999

South is 243 degrees to the right of the sun.
