1. Use your fingers to calculate remaining sunlight
If the display on your smartphone ever fails you, there are other digits you can use to tell the time—that is to say, your fingers.
Start by planting your feet towards the sun, extending one arm fully in front of you, and rotating your wrist so your palm is facing you horizontally. Close your fingers together and align your pinky with the horizon.
Now, count how many finger widths it takes to reach the sun. Depending on the season and time of day, you may need to continue stacking one hand over the other to keep count. Four finger widths represent one hour of sunlight, so unless you have exceptionally thin (or thick!) fingers, a count of eight finger widths during a southern Ontario July would equal two hours of remaining sunlight (roughly 7:30 p.m.).
