The US Open Tennis tournament is set to undergo a significant change in 2025, expanding to 15 days by starting on a Sunday for the first time in the Open era. The tournament, which traditionally began on the last Monday of August, will now kick off on Sunday, August 24, and conclude on September 7[2].

This change aligns the US Open with other Grand Slam tournaments like the Australian Open and the French Open, which have also adopted a 15-day format. The first round will be spread over three days (Sunday, Monday, Tuesday), but no further adjustments to the singles main draw schedule are planned after the first round[2].

The detailed schedule for the 2025 US Open includes various sessions, with day and night matches featuring men's and women's singles, doubles, and mixed doubles competitions. Key dates include the quarterfinals on September 2 and 3, the women's semifinals on September 4, and the men's and women's finals on September 6 and 7, respectively[1].

Fans can look forward to a packed schedule with plenty of action at the USTA Billie Jean King National Tennis Center in Flushing Meadows, Queens. The tournament will also include events for senior, junior, and wheelchair players, making it a comprehensive and inclusive tennis event[4].

For those planning to attend, gates will open at 9:30 a.m. until September 4 and at 11:00 a.m. from September 4 to 7. The US Open Fan Week, including the qualifying tournament, offers additional opportunities for fans to experience the event[1].

The 2025 US Open promises to be an exciting and extended tennis extravaganza, offering something for every tennis enthusiast.
