Good question.
“The 2022-23 English Football League season will start earlier on 30 July next year because of the World Cup.
The Championship will run until 12 November and resume on 10 December, but League One and League Two will continue without a mid-season hiatus.
The final round of fixtures in all three divisions will be played on the weekend of 6-7 May 2023, with play-off finals from 27-29 May.”
