The window in England has closed 24 hours before the new season kicked off for the last two seasons.
However, clubs feel they will benefit from a longer window, to sort out transfer business.
With August 31 being a Bank Holiday, the window will close 5pm on Tuesday, September 1 this year.
This ensures England is now in sync with the rest of Europe.
“At a shareholders’ meeting today, Premier League clubs voted to adopt a change to the summer transfer window closing date for season 2020/21.
“This will move the closing date back to the traditional point at the end of August/early September.
“The 2020 closing date will therefore be 17:00 BST on 1 September (31 August 2020 being a UK Bank Holiday).
“Clubs agreed after discussing the topic at length at previous Shareholders’ Meetings,” a Premier League statement read.
The Premier League also confirmed the 2020/2021 season will start on Saturday, August 8.
