Now It is Christmas time. We are celebrating the birthday of Jesus. On this occasion we can have a birthday puzzle.

• Take the month number of your birthday; Jan=1, Feb=2......
• Multiply that by 5
• Then add 6
• Then multiply that by 4
• Then add9
• Then multiply that total by 5
• Finally add the day you were born on
• From that number , subtract 165

Then you will get the month and the day you were born.

You can ask your friends to do it tell their birth dates and become a hero.
