  1. Kerry was born on 28th feb just before midnight, and her brother was born after midnight, i.e., march 1st. And the year she celebrated her birthday was a leap year. so the extra 29th of feb, brings in the delay of 2 days.

  3. Solution:
    At the time she went into labor, the mother of the twins was travelling by boat. The older twin, Terry, was born first early on March 1st. The boat then crossed the International Date line (or any time zone line) and Kerry, the younger twin, was born on February the 28th. In a leap year the younger twin celebrates her birthday two days before her older brother.

    This puzzle was submitted to Games Magazine’s ‘How Come’ competition in 1992 by Judy Dean. It won.
