#1 Different Birth Years:

Catalin and Valetin are twins from Romania who do not share the same birth day. Catalin was born prematurely in December and Valentin was born in February of the following year. This rare birth is attributed to a rare congenital condition in which their mother has a double uterus. One in every 50,000 women has a double uterus, but it is believed that this is the first case in which a woman was pregnant in both her uteri at the same time.
