Transfer window dates: how they actually work, league by league

"When does the transfer window open" doesn't have one answer — it has one answer per league, and getting it wrong by even a few days can mean a deal that's technically illegal to register, even if every party involved has already agreed to it.

Why every league sets its own dates

FIFA sets the outer rules — each association gets two registration periods a year, the first between eight and twelve weeks long and the second between four and eight, sixteen weeks combined at most — but the exact open and close dates are each league's own decision within that structure. That's why the Premier League's summer window doesn't close on the same day as Serie A's, and why Brazil's calendar, tied to its own season structure, doesn't line up with the European one at all. A deal that's fine to register in one league's window can be completely outside another's on the same calendar day.

The pre-contract exception that runs on its own clock

The transfer window governs when a club can register a new signing — it doesn't govern when a player out of contract can agree terms with a new club. That's the six-month pre-contract rule (covered in more depth in our piece on tracking contract expiries): once a player is within six months of their current deal ending, they can sign a pre-contract agreement with a new club at any time, window open or not. The move itself takes effect when the current contract ends, and the new club still has to register him — normally inside its own registration period, although FIFA's rules let a club register a player whose contract ended before that period closed even after it shuts.

What actually goes wrong when the dates are wrong

The two failure modes are opposites and both are costly. Missing a window's close date means a deal for a player still under contract, agreed in principle, can't be registered until the next window opens, months later — which can quietly kill a transfer that both clubs and the player wanted. Assuming a window is open when it isn't means wasted time negotiating something that legally can't be registered yet. Both come from the same root cause: treating "the transfer window" as one date instead of checking the specific league's specific calendar.

Where to check the current dates

Rather than repeat a static table here that goes stale the moment a league adjusts its calendar, GOAL-LINK keeps a live page with every tracked league's open and close dates and a running countdown — the same calendar our own platform reads internally, kept by hand from the dates the leagues publish, with any window that's still an estimate marked as one, rather than pulled from a summary that's quietly out of date.

For orientation: the summer 2026 windows in Europe and Brazil have closed. The Premier League's next window runs from 1 January to 1 February 2027 (23:00 UK time), and the other big European leagues also reopen in early January. In Brazil, the CBF's 2027 calendar sets the first window from 4 January to 2 March and the second from 19 July to 10 September.
