It isn't. To check, i knew that if a day in March, 2009 was going to be a perfect square, it'd have to be 17472 or 17532 (since it had to a little more than the sqrt(3,000,000) ~ 1732 and end in 009). Sure enough, turns out that today's date actually is a perfect square 17472 = 3052009.
April 1 this year also works (20032 = 4012009). After grabbing a calculator, i verified that August 98th and October 58th of this year also qualify.
The next one after that would be Feb 26, 2016.
