MacBook Pro Warranty: Validate purchase date

[maxwelltech]

Hi,
I got my 13 MacBook Pro (Mid 2012) about 2 weeks ago, from Amazon (Amazon.com, not some third party sellers). I went to the Apple support site yesterday, and I found out that my purchase date isn't validated. So, I validated it, and put June 24 (the day when I placed order) as the purchase date. The product was shipped out on June 25, and I received it (and registered it) on June 28.
Later, I realized that maybe I should put June 28 as the purchase date because that is the day when I actually start using the computer. Currently, the warranty is set to end on June 23, 2013 which is a few days short of one year. I validated the purchase date because I did not want any curveballs when using the Up-To-Date program to upgrading to Mountain Lion later this month.
Should I keep the June 24 date or should I switch to June 28, or June 25?

I know I am OK in the up-to-date program, but my question comes down to this: What is a purchase date? Is it my delivery date or order date?

I know online orders from Apple goes by shipping date. So if you can change it to a later date, why not? Get the most out of factory warranty because you're entitled to it with the purchase. But I don't know how you would go doing that, hopefully it'll work .
