It is 23 years since the two clubs have faced each other at the old Wembley, and the Scot believes that it will be a "special" occasion.
"It's magical to go to Wembley again. To take Everton to Wembley and to take them into a derby game as well is something special," Moyes told reporters.
"It hasn't happened that often. It used to happen a lot. I think the 1980s was probably the time when it happened most but I think to be the manager of Everton, take them back to Wembley again and to get the supporters there, I think that's special."
The winner of the match will face either Tottenham Hotspur or Chelsea in the FA Cup final.
