SEPTEMBER 28th is a special day. π
If you stand out in the sun at 12:45 PM, which is halfway between sunrise and sunset, you will CAST A SHADOW that is the SAME LENGTH as your height.
This is because at the midpoint of that day, the sun will have an angle of 45 degrees. The tangent of 45 is 1. Any number divided by 1 is equal to numerator.
