I mentioned a while back that we “unplugged” from devices at our recent camping trip: no GPS, no cell phones or laptops. The kids felt strange at first, but eventually got used to it.
Apt Prepper son used this trick he learned watching Les Stroud, Survivorman – to find out how much time is left until the sky goes completely dark. It was around 7 pm or so at the time, and he estimated around two hours and 15 minutes of daylight left. He estimated it would be dark around 9:15 pm. I had a solar watch and I checked the time to see if he was accurate. I thought that seemed really late but I waited to see if it would really work.
After the sun finally went down and it was pitch black, I checked the time: 9:15. The method was amazingly accurate.
Hold your arm and stick your hand out. Place your hand between the sun and the horizon. Each finger represents 15 minutes, and four fingers will equal one hour. If you can stack your hands twice then that is two hours and so on. In our case, at around 7 pm, Apt Prepper son was able to stack his hands twice plus one finger between the sun and the horizon, thereby coming up with 9:15 pm.
This method can be a lifesaver if you are out in the wilderness without a way to tell time. You can gauge how much daylight you have left so you can return back to base camp in a timely manner.
