This is just how javascript understands dates...
You'd find even less that were born in 2011... I'm sure they couldn't see a screen.
You could create a dropdown list instead of having them type in a date.
The reality is that if you looked at every time in history someone has referred to a date with '11 as the year... the majority are still talking about 1911. The standard is to use a four digit date after the year 2000. This is how computers work in general, be it javascript, vbscript, php, asp, sql, or any other computer language that I have used.
Did this help? Tips are appreciated...
