As In understand it (which is to say, not very well), publishing release dates are not usually strictly enforced unless it's something like Harry Potter, where they're trying to create huge buzz by withholding the book until midnight (which seems kind of misguided to me, but...sorry, off on tangent).

Last week I bought a book which was not officially out yet -- many bookstores just put them on the shelf when they come in. So...I'd start checking around March 20.
