Kick-off times in major competitions are decided by broadcasters rather than by clubs. The arrangement follows directly from how the competitions are funded.
What a broadcast deal actually buys
Rights agreements grant a number of matches per season together with the right to choose which ones and to place them in specified slots.
Spreading fixtures across a weekend produces several exclusive windows rather than one crowded afternoon, which raises the value of the package considerably.
The competition sells that flexibility because it is a large part of what makes the rights valuable, and the money is distributed to the clubs. A package without selection rights would be worth materially less, so the flexibility is priced into every deal.
Why selections are made late
Broadcasters want the most attractive fixtures, and which matches those are depends on how the table develops through the season.
Selections are therefore confirmed only weeks in advance, within a notice period agreed in the contract.
That notice period is the central point of negotiation for supporter organisations, since it determines how much time exists to arrange travel. Fixtures late in a season, where the stakes are highest, are also the ones most likely to move.
The cost falls on travelling supporters
A match moved to a late evening or an early morning can leave away supporters without public transport at either end of the journey.
Advance travel booked before a change is announced may be non-refundable, so the cost of the move is borne by individuals.
Clubs sometimes subsidise coaches for rearranged fixtures, which acknowledges the problem without addressing the scheduling that causes it. The subsidy is funded from the same broadcast income that produced the change in the first place.
International markets pull the other way
Overseas audiences are now a substantial part of rights income, and their viewing hours differ from those of the domestic audience.
Early kick-offs that suit distant time zones are unattractive locally, and the schedule reflects a compromise between the two.
As overseas income grows relative to domestic, the balance of that compromise shifts, which is the underlying reason slots have kept moving.
The protections that exist
Some competitions maintain blocked periods during which no match may be broadcast, originally intended to protect attendance at lower levels.
Minimum notice periods and limits on how often a single club can be selected are also written into agreements.
These are negotiated rather than fixed, and each rights cycle reopens the question of how much scheduling freedom is being sold. Supporter groups now lobby during that process rather than complaining after the calendar is published.
