The FA Cup final between Manchester United and Crystal Palace on 21 May, which will be shown live on BBC One, will kick-off at 17:30 BST.
Gary Lineker will present live coverage from Wembley as 11-time winners United look to secure their first FA Cup triumph since 2004 and Palace seek to win it for the first time.
There will be dawn-to-dusk coverage of the final across BBC One, BBC Two, Radio 5 live and the BBC Sport website.
Mark Clattenburg is to referee the tie.
The tie is a repeat of the 1990 final when Sir Alex Ferguson's United won the replay 1-0 after a 3-3 draw.
United will wear white shirts, black shorts and white socks at Wembley and Crystal Palace will wear their traditional red and blue home colours.
More than 57,500 supporters of the two finalists will be at Wembley, according to the FA, up from 50,000 in 2015.
A statement on the FA website said: "The increase will see 28,780 tickets per team, the equivalent of 80% of the available seats in the stadium."
Ticket prices across all price points have been reduced by £5, with prices at £45, £65, £85 and £115.
Palace fans will be situated in the west side of Wembley, with United fans occupying the east side.
