Clubs will be able do business from Wednesday January, 1 up until 11:00pm GMT on Friday January, 31.
It has also been announced that Premier League clubs will be given an extension to finalise their 25-man squad for the second half of the campaign due to a round of fixtures on January, 30.
The Premier League has confirmed the dates and times for the January transfer window
Usually, clubs have to register their squads for the remainder of the season the day following the transfer window, but because deadline day is only a day before scheduled fixtures, the deadline for submission has been pushed back to Wednesday February, 5.
In a statement on Thursday, the Premier League said: ‘New players signed on 1-2 January will not be eligible for Matchweek 21, but they can be made available for the following Matchweeks as clubs are permitted to make changes to their squad lists throughout the January window.
‘Clubs completing deals late on Deadline Day, 31 January, will be able to submit a Deal Sheet between 21:00-23:00 GMT.
‘Clubs will have until midnight on Deadline Day to complete the information needed by FIFA’s Transfer Matching System to apply for international clearance for new signings.’
