# Math Riddle Involving Birthdays [closed]

So someone asked me the following riddle:

If a girl is born in the 19th century, and on her first birthday she is 8. How is this possible? I think it's a simple mathematics problem but I can't find a way to figure it out.

Presumably something to do with February 29? – Zev Chonoles Nov 21 '11 at 2:41
@Zev: Feb 29, 1896, to be precise. – cardinal Nov 21 '11 at 2:42
