The 2026 MLB regular season started on Wednesday, March 25, 2026. That night, the New York Yankees visited the San Francisco Giants in the standalone MLB Opening Night game at Oracle Park. Traditional Opening Day followed on Thursday, March 26, when most of the league played its first game.
So, if you searched “When does MLB season start 2026?” and found both March 25 and March 26, neither date was necessarily a mistake. March 25 was the precise start of the championship season; March 26 was the date MLB labeled traditional Opening Day. Because both events have already happened, this guide uses the official results and past tense. For the schedule still ahead, use the complete 2026 MLB schedule.
What date did the 2026 MLB season start?
The first game that counted in the 2026 regular-season standings took place on March 25. The Yankees beat the Giants 7-0 in San Francisco, confirming that Opening Night was a real regular-season game—not a ceremonial exhibition before the season.
MLB then spread the rest of the league's first games across March 26 and March 27. That created three useful answers, depending on what a fan means by “start”:
| 2026 opening milestone | Date | What it answers |
|---|---|---|
| MLB Opening Night | Wednesday, March 25 | The first official game of the 2026 regular season |
| Traditional Opening Day | Thursday, March 26 | The main league-wide opening date, with 11 games actually played |
| Final team openers | Friday, March 27 | The day the remaining six clubs began their seasons |
| First full 15-game slate | Saturday, March 28 | The first day all 30 clubs were scheduled to play, not the season start |
The cleanest short answer is therefore March 25 for the MLB season, March 26 for traditional Opening Day. If you need the games being played now rather than the historical opening slate, go directly to today's MLB games.
Why do March 25 and March 26 both appear as Opening Day?
MLB deliberately used two related labels. The official schedule release called Yankees-Giants on March 25 a standalone Opening Night, then called March 26 Opening Day. The first term describes the one-game launch of the regular season. The second describes the traditional day when baseball opens across most of the league.
It helps to match the date to the exact question:
- When was the first MLB regular-season game? March 25.
- When was traditional MLB Opening Day? March 26.
- When did my team open? March 25, 26 or 27, depending on the club.
March 26 also carried a historical distinction. MLB said it was the earliest traditional Opening Day in Major League history, excluding special season openers and international openers. The previous record had been March 27 in 2025. The early master schedule initially described 14 March 26 games; MLB's later game-times announcement and the games actually played produced an 11-game slate. That is a useful reminder that detailed schedules can change after the season framework is announced.
When did all 30 MLB teams begin their 2026 seasons?
Not every club began on the same date. The Yankees and Giants accounted for the two teams active on March 25. Eleven games on March 26 gave 22 more clubs their first regular-season action. The final six teams opened on March 27, when the Athletics visited the Blue Jays, the Rockies visited the Marlins and the Royals visited the Braves.
That three-day rollout explains why a club's “Opening Day” can differ from MLB's overall season start. It also explains why searching only the March 26 schedule would miss six team openers even though March 26 was the traditional opening date.
How to find your team's first game
For a quick historical check, open the full schedule and filter by team, then move to the earliest date. If you want a paper copy or a PDF, the full-league printable MLB schedule lets you filter the complete regular-season list before printing. That is more useful than reproducing a static 30-team table here because it also shows the rest of each club's schedule.
Remember that a team's home opener is not always its season opener. A club can start on the road and hold its home-opening ceremony days later. When checking a team, look at the away and home labels rather than assuming its first home date was its first regular-season game.
Did Spring Training count as the start of the MLB season?
No. Spring Training supplied preseason baseball, but its results did not count toward a club's 162-game regular-season record. MLB's official Spring Training announcement separated the calendars clearly: Cactus and Grapefruit League play began on February 20, while the regular season began with Opening Night on March 25.
The distinction mattered more than usual in 2026 because several baseball events filled the weeks before Opening Night:
- Spring Training: MLB clubs prepared in Arizona and Florida beginning February 20.
- MLB club-WBC exhibitions: clubs played national teams in warmup games on March 3 and 4.
- World Baseball Classic: the international tournament ran separately from MLB team standings.
- Spring Breakout: prospect exhibitions took place from March 19 through March 22.
Those games were meaningful preparation or separate competitions, but they did not move an MLB club to 1-0 or 0-1 in the regular-season standings. For schedule-counting purposes, March 25 was the line: the Yankees-Giants result was the first one included in the championship season.
How long is the 2026 MLB regular season?
Each MLB club was scheduled to play 162 regular-season games. Across 30 clubs, that produces 2,430 games: multiply 30 by 162, then divide by two because every game appears on two teams' schedules.
On the calendar, the 2026 regular season runs from March 25 through Sunday, September 27. Teams do not play every day in that window. Scheduled off days, travel days, the All-Star break, doubleheaders and weather-related postponements all shape the path from Game 1 to Game 162.
September 27 is the planned regular-season finish, not the end of baseball for playoff qualifiers. For the distinction between the regular-season finale and the postseason, read the separate guide to when the 2026 MLB regular season ends. Keeping that topic on its own page prevents the Opening Day answer from being buried under October format details.
How to find the schedule after Opening Day
Opening Day is now a historical date, but the useful part of the schedule changes every day. Choose the view that matches what you want to do:
- Find a channel for an upcoming game: check the MLB TV schedule, where current broadcast and streaming assignments belong.
- Print every matching game: use the printable page linked above, apply your team or date filters, and print all filtered results rather than only the visible page.
- Work in Excel or Google Sheets: use the MLB schedule download tool to export filtered regular-season games as CSV or TSV.
- Add games to a calendar: choose the ICS option on the download page instead of manually copying dates.
A saved schedule is a snapshot. First-pitch times, television assignments, venues and postponed games can change during the season, so generate a fresh download or revisit the live pages before making a trip or planning what to watch. This article answers when the season started; the tools handle what is happening next.
