While relegation beckons for some, May is often more memorable for promotion battles and there have been some considerable shocks in recent years.
With the possibility that 1/2 Notts County could miss out on promotion from the National League to a team in 25/1 Bromley that finished the 46-game regulation season 36 points behind them, now seems the perfect time to assess the biggest upsets in the history of both the EFL and non-league playoffs.
Some are journeys, some are one-off results, but the truth remains: regardless of a team's division, getting to the playoffs counts for nothing if they do not see the job through.
5) 2009/10 - Championship - Blackpool
A run that proved just how important momentum can be, Blackpool's ascent to the top flight for the first time in 39 years looked incredibly unlikely when with eight games to go, they found themselves seven points behind the final playoff spot, having played a game more than sixth-placed Cardiff.
However, after taking over at Christmas, Ian Holloway's unique approach in the run-in helped his side win six of their last eight matches to take sixth, a point ahead of Swansea.
After a pulsating 6-4 aggregate semi-final win over third-place finishers Nottingham Forest, Holloway's side headed to Wembley to take on Cardiff.
Despite twice going behind before half-time, the Tangerines triumphed 3-2 to mark a magnificent decade that started with them also being promoted through the playoffs, but this time from the bottom tier.
4) 2015/16 - League One - Barnsley
Paul Heckingbottom has just guided Sheffield United to promotion to the Premier League but arguably his greatest achievement as a coach was taking Barnsley from League One and into the Championship.
The lifelong fan took charge in February after Lee Johnson had departed for Bristol City, Johnson himself having lifted the team from 21st on Boxing Day and up to 11th after taking 28 points from a possible 33.
Heckingbottom took over and guided the team to both the EFL Trophy and sixth in the standings.
That momentum allowed them to upset Walsall, whom they finished 10 points behind, in the semi-finals before beating Millwall 3-1 at Wembley.
The Tykes became the first side to win promotion having been in the relegation positions at Christmas and Johnson and Heckingbottom deserve to share the credit for a remarkable success.
Barnsley are again in the League One promotion reckoning this season and are 11/4 To be Promoted.
3) 2011/12 - National League - Luton 2-0 Wrexham
Similar to this season, when they finished four points head of Notts County, Wrexham were the best of the rest in the National League in 2011/12, closing the campaign on 98 points, five behind champions Fleetwood.
There was even an outcry suggesting they should be given promotion automatically, but they fell short when it mattered.
Despite finishing 17 points ahead of Luton in the final standings, it was the Hatters who came out on top over two legs.
Future Burnley and Watford star Andre Gray was among the Luton goalscorers in a 2-0 first leg win at Kenilworth Road, before George Pilkington's penalty put the visitors 1-0 ahead at the Racecourse Ground.
Despite a second-half fightback from the Dragons, it was not enough.
Luton could not finish the job, losing 2-1 to York at Wembley, although they have been on a real journey over the last decade, and are 5/2 To Be Promoted from the Championship this season.
2) 1998/99 - Division One - Charlton 4-4 Sunderland (7-6 p)
It seems strange to suggest a side who finished just two points behind their Wembley opponents caused a shock but that was the feeling when Charlton beat Sunderland 7-6 on penalties following a spellbinding 4-4 draw.
The Black Cats were playing their first season at the Stadium of Light and, alongside champions Nottingham Forest and second-placed Middlesbrough, seemed head and shoulders above the rest of the division.
However, Charlton's run of nine straight clean sheets on the way to Wembley marked them out as contenders, as did striker Clive Mendonca, who scored 25 regular-season goals and then smashed in a hat-trick at Wembley.
Still, Sunderland's team, which included the likes of Niall Quinn, Kevin Phillips and Lee Clark, always felt like they had the edge, almost until Michael Gray stepped up and saw his low penalty saved by Sasa Ilic.
1) 2016/17 - Championship - Huddersfield 0-0 Reading (4-3 p)
Perhaps one of the greatest stories of recent years was Huddersfield's rise to the top flight thanks to a penalty shootout win over Reading.
While they were only four points behind the Royals in the final standings, there still seemed something unreal about a team who had finished the previous season 19th in the table and had not played in the top flight since 1971/72.
Huddersfield held their nerve in the semi-finals to beat Sheffield Wednesday on spot-kicks and followed it up at Wembley, where they were second best for the majority of a cagey 120 minutes.
Reading scored their first three penalties, while Michael Hefele missed for Huddersfield.
However, failures from Liam Moore and Jordan Obita allowed Hefele's fellow German central defender, Christopher Schindler, to stroke home the winner and send Wembley, and Kirklees, into raptures.
