You know the knuckle trick, right? (Punch someone until they tell you? No, no..) Make fists, fingers away from you and thumbs tucked under fingers. Put hands together, index fingers touching along their (curved) length. Now count knuckles and gaps between knuckles, leaving out the gap between hands. Like this: Left pinkie knuckle - up, 31 days, January. Space - down, 28(9) days, February. Left ring finger knuckle - up, 31 days, March. Space - down, 30 days, April .... Left index finger knuckle - up, 31 days, July. Right index finger knuckle - up again, 31 days, August space on right hand - down, 30 days, September Right big finger knuckle - up, 31 days, October ..... HTH, - Mark
