How to Estimate Remaining Daylight

On my search through the vast internet, I came across this picture to estimate remaining daylight using just your fingers.  In the survival handbooks I read, I have yet to run across this bit of information. 

Survival techniques not are an emphasis of this blog; however, I feel this information should still be shared with my loyal followers.

To ease the reader the captions states:

"Count the finger widths between the sun and the horizon.  Each finger is equivalent to fifteen minutes, with each hand totaling an hour. When the sun dips low enough that only two hands fit, its time to search for a suitable campsite and assemble shelter. (A caveat: if you're near the poles, the sun will hover over the horizon for a longer period of time, giving you an inaccurate reading.)"



As with any survival gear, gadget, or technique try this at a time of leisure.  Your fingers might be 10 minutes width or 20 minutes width, giving you an inaccurate reading.  Don’t put yourself in a survival situation and expect spot on results.  Practice to be ready for when the time arrives.
