The fixture list for the 2014/15 season will be announced on Wednesday 18 June at 09:00 BST.
The first set of changes take place when television companies select the first group of matches they would like to screen live. This usually happens within a few weeks of the original list coming out.
At around the same time, the clubs that are playing in Europe will examine the list to see if there are any matches which need to be moved. Once teams progress to the later rounds of the other cup competitions, League fixtures can be altered. In this instance we always consult with the local police and the clubs concerned.
