If the stars in the northern sky are visible, says Popular Mechanics, you can set your watch by them within fifteen minutes of the correct time and without the use of a complicated table. The polestar is considered as the center of a huge clock and the pointer of the Dipper, the hour hand. The numeral six will be below the polestar and twelve above. Taking the time as indicated by the Dipper's pointers, you can add to that figure the number of months that have elapsed sice the first of January to the nearest quarter month. The resulting sum is doubled and subtracted from sixteen and a quarter. If the result is more than sixteen and a quarter, subtract it from forty and a quarter. The answer is time in hours after noon. For instance, it is late September and the pointers of the sky clock correspond to the position of the hour hand at seven o'clock. Eight and three-fourths months have elapsed since New Year's Day. This is added to seven, making fifteen and three-quarters. Double this is thirty-one and one-half. Subtracting from forty and one-quarter gives eight and three-quarters, or 8:45 P.M.
