Read it through once

Another Reason may be given why there cannot be supposed to be a great Length of Time in this Play; which is this, That we see in the First Act, Ambassadors dispatch'd to old _Norway_, concerning his Nephew _Fortinbras's_ Army, which was then ready to march; and in the Fourth Act, we see this Prince at the Head of that Army, which immediately, upon the Embassy from the _Danish_ King to his Uncle, we are naturally to suppose he leads to that other Enterprize which is mentioned in that Scene. Now it is no ways likely, that between the Embassy and the marching of an Army already assembled before that Embassy, there should be a Number of Years. These Reasons and the whole Conduct of the Piece convince me, that this is one of _Shakespeare's_ Plays, in which the least Time is employ'd; how much there is, I cannot pretend to say.
