The date 2012-02-30 using the (very short lived) Swedish calendar is still a 
valid date just as the day 17th of Av 5771 (5771-05-17) is a valid date 
(today, at least here for the next few minutes as the Sun comes to set) in 
the Jewish calendar. In the International calendar, however, the year is 
2011 and not 5771, the month is August, the 8th month and not Av.. and Feb. 
never has 30 days...
