Usually 24 hours, depending on temperature and humidity. If it is excessively hot, you could walk on it sooner, and if it is cold or damp, you might want to give it a little longer. If it is hot, you might want to consider covering the concrete with plastic a couple of hours after finish, so that the moisture will not excape too rapidly, causing the concrete to shrink and crack. If you are going to put a lot of weight on the concrete, such as a car, wait at least a week, to be safe.

Depending on what kind of sealer you use, the concrete should be completely dry and firm enough to walk on. However, I know of at least one concrete sealer (Concrete Treat) that can be applied immediately after the concrete has been placed -- with no wait at all for curing. Check out the products as you go and see what might work best for you. See the attached link.
