Sheffield Wednesday will get the Championship play-offs under way after the Football League released the running order for its matches.
The Owls know they will finish sixth in the table and they will host the third-placed team, which will be either Middlesbrough or Brighton, on Friday, May 13 with the return leg taking place on Monday, May 16.
Middlesbrough host Brighton at the Riverside on Saturday in a final-day shoot-out for the second automatic promotion place along with Burnley.
The other tie will be between Hull and Derby, although which way round they will finish in the table is yet to be decided.
Hull are currently fourth and two points ahead of Derby and will hope to keep it that way as it would mean they have the second leg at the KC Stadium on Tuesday, May 17, with the first leg scheduled to take place on Saturday, May 14.
The first match of the League One play-off semi-finals will be contested between the sixth-placed side and the third-placed team on May 14. Either Barnsley, Scunthorpe or Gillingham will host Burton, Walsall or Millwall and the return leg will be on Thursday, May 19.
Bradford are guaranteed to be involved in the other tie but could yet finish fourth or fifth and the Bantams’ opponents could be either Millwall or Walsall. The first leg of that tie will be on Sunday, May 15 with the return leg on Friday, May 20.
In League Two, AFC Wimbledon are certain to finish seventh and they now know they will be at home to either Accrington, Oxford or Bristol Rovers on Thursday May 12, ahead of a second-leg trip on May 15.
The other tie will definitely be between Portsmouth and Plymouth on May 14 and 18 but with both teams level on 78 points going into the final game of the season on Saturday, their final positions in the table have yet to be decided.
