MLS confirmed the details of the full 2021 schedule on Wednesday, with each of the league's 27 teams set to play 34 games this season.
The league, which welcomes Austin FC for the club's inaugural campaign, will kick-off on April 17 with seven consecutive weeks of games before the June international break.
As a result of the coronavirus pandemic, this season's MLS schedule is focused heavily on intra-conference regional play as it runs towards a November finish.
How does the 2021 MLS Schedule work?
Each of the league's 27 clubs are set to play 34 games, 17 home and 17 away, over the course of the regular season, which runs from April until November.The 14 teams that make up the Eastern Conference will play each of their six regional opponents three times and the seven remaining Eastern Conference opponents twice, accounting for a large majority of their schedule with only two cross-conference games.
In the Western Conference, meanwhile, the schedule will look slightly different due to the odd number of teams. As a result, two Western Conference teams will play three cross-conference games this season.
