At the beginning of the play Theseus tells Hermia that she has THREE days to make up her mind. However, when Theseus tells Egeus that the day is arrived for her to make her decision, only two days have passed!
I should clarify this-
*Theseus tells Hermia that she has three days to make up her mind.
*Hermia runs away that night with Lysander.
*They wake the next morning.
*Theseus announces that the day is due.
Now I can't see how that makes three days when it turns out that it was the next morning, even if he was counting the previous day.
