<Tr> <Td> 1 December--31 January </Td> <Td> 1--30 June </Td> <Td> Ethiopia </Td> </Tr> <P> Premier League clubs in England voted to end the summer window on the Thursday before the start of the season - on August 9 in 2018, instead of August 31 . Because FIFA demands the window must be open for 12 weeks, the window will open around May 17, shortly after the final games of the season on May 13 . Clubs will be able to sell players until August 31 but not buy replacements after the deadline of August 9 . </P> <P> Although, in England, transfers between clubs in the same league can take place as soon as the last competitive fixtures for the season have been played, many transfers will not be completed until 1 July because many players' contracts expire on 30 June . International transfers into the English leagues (including the Premier League) cannot be made until the window has opened on 17 May . Outside the transfer window, a club may still sign players on an emergency basis, usually if they have no goalkeeper available . Special dispensation from their competition's governing body, for example the Premier League, is required . The transfer window restriction does not apply to clubs below the National League division . </P> <P> If the last day of a transfer window is on a weekend, the deadline can be extended to the following Monday at the request of those involved for business reasons . The first shift of the deadline since its inception took place in summer 2008, when the deadline was extended by 24 hours to fall on Monday 1 September at midnight . The transfer deadline in England was similarly extended to 5 pm 1 September 2009, due to the August Bank Holiday . The German football league announced an extension of the January 2009 deadline to 2 February . </P>
