For example, if you counted 4 hands and 2 fingers, then you have approximately 4.5 hours left until sunset.

Keep in mind that this will still only give you a rough estimate of the remaining time in a day.

Once you've reached the horizon, you can also count how many fingers could fit in the space between the sun and horizon if you can’t fit a whole hand there. This is also helpful if you cannot fit your whole hand between the sin and the horizon. In this case, you will only need to count the fingers between the sun and horizon instead. Each finger that will fit in this space represents 15 extra minutes before sunset. Multiply the number of fingers by 15 and add this to the number of hands you counted.
