Major League Soccer will change its competition calendar to run from July through May starting in 2027 [1, 2].
This shift represents a fundamental change in how professional soccer is structured in North America. By moving away from the traditional spring-to-autumn format, the league aims to integrate more seamlessly with the international soccer community and the transfer windows used by global clubs.
The league's board of governors approved the change to better align the MLS calendar with the global soccer calendar [1]. This realignment is intended to reduce direct competition with other major North American sports seasons, which typically dominate the autumn and winter months.
Under the new format, the first season utilizing this schedule will begin in 2027 [2]. While the league has confirmed the season will kick off in July, an exact date has not yet been specified [1]. The shift will affect all clubs based across the U.S. and Canada [1].
Historically, MLS has operated on a calendar that differs from most top-flight leagues in Europe and South America. This discrepancy often created challenges for players moving between leagues and affected the timing of roster adjustments. The new July–May window [1] is designed to resolve these systemic frictions.
The league said further details regarding the transition would be available on July 13.
“MLS will change its competition calendar to run from July through May starting in 2027.”
The transition to a July–May schedule signals MLS's ambition to move beyond its status as a regional outlier and become a fully integrated part of the global football ecosystem. By mirroring the European calendar, the league can more effectively attract international talent and simplify the logistics of player transfers, while simultaneously carving out a distinct broadcasting window that avoids the peak congestion of the NFL and NBA seasons.
