The witches first meet in Act 1 scene 1 of Macbeth asking just that question with the famous "When shall we three meet again?" as the Scottish nobility fight and slaughter each other around them.

The answer is "When the hurlyburly's done, When the battle's lost and won" which means by sunset that day according to the third witch's prophecy.

The reason that they are to meet again is simply "There to meet with Macbeth".
