month-fist - The figure shows how to identify a given month if it's a less than/equal to or more than 30-day month. This starts from counting whether in forward or backward direction. The emerging bones of the fingers when our hand is close represents all months that are 31 days while the in-betweens are those less than or equal to 30 days. I was so amazed when I knew that c/o my father. I thought then that those simple closing of our hands have such meaning on the our calendar months. I thought then also that our fist is intended only for boxing or fighting (hitting someone or something). But God indeed created us (even our smallest body parts) with a purpose!
