Just wondered this.
What happens when someone is born on the 29 of Feb? How does SMF handle that? I mean the Info Center part, that is. Would age be correct? o.o;
I cant really say about the Info Center since Feb 29, 2008 has passed. :P
But for the Calendar area, it is calculated correctly, (eg, Feb 29, 1984 would equal 24 years) in the calendar, but on non leap years, it is not moved from Feb 29 to March 1.
