ha or you can download thumbcal

It replaced my calendar in touchflo3d and when it opens it starts in day view... if you slide your finger left/right it goes to the previous/next day.
Oh and thumcal is so much more finger friendly than the default calendar.. you'll love it.
I'm using the trial now... not sure if it expires.. might just have the annoying "unregistered demo" care to buy message that pops up at first launch until you buy/register.
