The 3 Critical Days: Your Complete Guide To What Days 'Big Brother' Is On (Updated For 2025)

For dedicated fans of Big Brother, knowing the exact weekly schedule is crucial, as missing an episode means missing a major power shift in the house. The structure of the show, which airs multiple times a week, is designed to give viewers a complete picture of the Houseguests' political maneuvering, from the Head of Household (HoH) competition to the dramatic Live Eviction. As of December 12, 2025, the most recent full season, Big Brother 26, has concluded, but the show maintains a highly consistent three-day-a-week schedule that will almost certainly be adopted by the upcoming Big Brother 27 (BB27) season in Summer 2025.

The American version of Big Brother (BB) typically runs throughout the summer, delivering three brand-new episodes every single week on the CBS network and streaming live on Paramount+. While the exact time slot can sometimes shift an hour early or late, the three core days of the week remain the same, giving fans a reliable pattern to follow. This deep dive breaks down the essential days, what to expect in each episode, and the critical internal schedule that drives the Live Feeds.

The Official Big Brother Weekly Broadcast Schedule

The Big Brother US schedule is a consistent three-episode-per-week format that has been the backbone of the show for years. This structure ensures every major event—the acquisition of power, the nominations, and the final vote—is covered in its own dedicated broadcast. For the most recent and upcoming seasons, the schedule is centered around the weekend and the middle of the week.

The three main days for a new episode of Big Brother are:

• Sunday Night: The Power Episode (HoH & Nominations)
• Wednesday Night: The Veto Episode (Power of Veto Competition & Ceremony)
• Thursday Night: The Live Episode (Eviction & Next HoH Competition)

While the exact timing for the upcoming Big Brother 27 season in 2025 has not been officially locked down by CBS, based on recent seasons, fans can expect the show to air in the following time slots:

Decoding the Big Brother Weekly Cycle: What Happens on Each Day?

The three episodes per week are not just random recaps; they each cover a specific, crucial 48-hour period in the Big Brother house. Understanding the events that correspond to each day is key to following the strategy and drama.

Sunday: The Power Episode (HoH & Nominations)

The Sunday episode is where the power in the house officially shifts. It’s the starting point of a new week of gameplay.

• Head of Household (HoH) Competition: The episode typically opens by concluding the HoH competition that began immediately after the previous Thursday's Live Eviction. The winner gains control of the house for the week.
• HoH Room Reveal & Strategy: The new HoH moves into their private room, receives letters from home, and begins plotting their nominations. This is where the alliances and targets for the week are established.
• Nomination Ceremony: The episode culminates with the Nomination Ceremony, where the HoH must nominate two Houseguests for eviction. This sets the stage for the rest of the week's drama.

Wednesday: The Veto Episode (Power of Veto)

The Wednesday episode is often the most suspenseful, as it introduces the chance for the nominated Houseguests to save themselves.

• Power of Veto (PoV) Competition: The core of this episode is the Veto competition, where the HoH, the two nominees, and three randomly selected Houseguests compete for the coveted Power of Veto.
• Veto Strategy: A significant portion of the episode is dedicated to the behind-the-scenes drama, pleading, and deal-making as Houseguests try to convince the PoV winner to use (or not use) the Veto.
• Veto Ceremony: The episode ends with the Veto Ceremony. If the PoV winner uses the Veto, one of the original nominees is saved, and the HoH must name a replacement nominee, locking in the final two Houseguests for the Thursday eviction vote.

Thursday: The Live Episode (Eviction Night)

Thursday is the most critical day of the Big Brother week. The episode is broadcast live, meaning the outcome is decided in real-time.

• Final Appeals: The two nominated Houseguests are given a final opportunity to make a public appeal to the other voters.
• The Vote: One by one, the non-nominated Houseguests enter the Diary Room to cast their vote to evict one of the two nominees. The host, typically Julie Chen Moonves, announces the results.
• Live Eviction: The Houseguest with the majority of votes is immediately evicted from the house and sits down for a live, post-eviction interview with the host.
• Next HoH Competition: The episode usually concludes with the start of the next HoH competition, which is often an endurance challenge that continues on the Live Feeds.

The All-Important Live Feeds Schedule: The Hidden Days of Big Brother

For the most dedicated fans, the official three-day broadcast schedule is only half the story. The 24/7 Live Feeds, available on Paramount+, provide continuous coverage and reveal the events that happen between the episodes. The Live Feeds follow a strict, internal schedule that is consistent every week, regardless of the broadcast days.

This internal schedule is what truly dictates the flow of the game:

• Thursday Night/Friday Morning: The Live Feeds return shortly after the Thursday Eviction show concludes, showing the immediate aftermath and the conclusion of the new HoH competition.
• Friday: The new HoH holds the Nomination Ceremony. This event is often blocked from the feeds (a "Feed Block") and the results are revealed when the feeds resume.
• Saturday: The Power of Veto Competition is held. This is always blocked from the feeds, and fans wait for the feeds to return to learn the PoV winner.
• Monday: The Veto Ceremony is held. This is the final chance for the nominees to be saved, and the final nominees are locked in for the week. This is also blocked from the feeds.
• Tuesday/Wednesday: These days are dedicated to campaigning, strategy, and last-minute deals leading up to the Thursday Live Eviction.

By following this consistent weekly pattern—Sunday for power, Wednesday for safety, and Thursday for the vote—you can ensure you never miss a critical moment in the high-stakes game of Big Brother.
