Guess Your Birthday

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.
