One day Kerry celebrated her birthday.

Two days later her older twin brother, Terry, celebrated his birthday.

How can this be, assuming that the difference in twins' ages can be a few minutes, but not over an hour?

Leap year - one was born just be fore midnight Feb 28, the other just after on Mar 1, and every leapyear their birthdays are a couple days apart.
