Date When Celebrated: Always January 9th. Research did not discover any information on the meaning or purpose of this day. What wei do know, is that God is good. Therefore, I believe that Play God Day is a day to do something good and extra special. To mark this day, I suggest that you do something good that will make a difference. Anything that fits this definition is appropriate. You do not have to make it something miraculous. It can be something simple, like visiting someone who is ill, or helping someone in need. Giving God thanks or a prayer is also appropriate for this day.
