Most exterior doors swing in. It is possible to special order outswing exterior doors, but they are not nearly as common.

If this door is for your house, or any building you plan to heat or cool, and if you don't live in Hawaii, I'd strongly discourage trying to modify an inswing door to an outswing. You will have a hard time getting the weathersripping and waterstop features to work right after flipping the door around. With the cost of energy due to keep rising for the forseeable future, you don't need to be stuck with a leaky exterior door down the road just because you couldn't wait the two weeks now. Put up a temporary construction door in the interim, to keep the critters and bad guys out.
