Josiah & Abi's Flight Log

Ok, here is a little riddle that I came up with. I hope you like it.
Last winter we were down in Florida at a having breakfast at a restaurant, the date was March first and we were celebrating my brother Andrew’s birthday. For on March first Andrews birthday was yesterdays tomorrow, but it was not on that day, that day being march 1st. How can that be? And when is Andrews birthday?
