The Major League Soccer Board of Governors have voted to align MLS with the international soccer calendar by shifting the regular season to a summer to spring schedule beginning in 2027.
Currently, MLS currently plays on a February to November calendar.
The change will result in the season kicking off in mid July and running through the Spring, with Decision Day in April and the MLS Cup playoffs in May.
MLS will allocate a winter break from mid December to early or mid-February.
This will enable MLS to sync up with the international transfer windows, so MLS teams can participate in the global transfer market.
As it currently stands, the MLS primary transfer window runs from January 31 to April 23, while most international leagues have player transfers during a traditional summer window.
MLS will run a shortened season in 2027 from February to May, where an MLS Cup champion will be crowned before the league officially shifts to the new calendar in summer 2027.
