One Way to Find the Number of Days in the Month
Count the knuckles of the hands, with the spaces between them; all the months with thirty-one days will fall on the knuckles, and those with less than thirty-one in the spaces. Thus, beginning with the forefinger of the left hand, July will come on the knuckle of the little finger; then beginning with August on the forefinger of the right hand, December will be reached at the knuckle of the third finger.
