CHRISTMAS BIRTHDAYS
At the Hetherington family gathering over Christmas, Dad commented: ‘Something strange seems to be happening to our family’s birthdays. Have you noticed how New Year’s Day comes exactly one week after Christmas Day? Yet the year Mum was born, Christmas was on a Tuesday and New Year was on a Monday. And Damien, two days ago you were eight years old, yet next year you will be eleven. And Janet seems to be extremely lucky. Even though she was also born soon after Christmas, her birthday is always in the middle of summer.’
The family groaned. What date was it, and how do you explain the strange birthdays?
