Big Brother 27 is tweaking its routine as the season hits the home stretch, and viewers should be ready for a shifting schedule. With only five houseguests left, host Julie Chen Moonves outlined later start times, longer episodes, and a few special event swaps to steer clear of sports and fall premieres. Here are the specifics fans need to set their reminders.

What’s changing this week

The show’s usual nights remain Sunday, Wednesday, and Thursday at 8/7c, but several late‑September airings move around:

  • Sunday, September 21, 2025: The Sunday broadcast slides to 10/9c due to football preemption.
  • Wednesday, September 24, 2025: A special eviction replaces the standard episode.
  • Thursday, September 25, 2025: Eviction night still begins at 8/7c but runs 90 minutes.
  • Sunday, September 28, 2025: The finale starts at 8:30 pm ET / 7:30 pm CT and is extended by an extra half hour.

Some broadcasts no longer fit the standard 60‑minute runtime. The network is stretching or shifting certain nights to avoid clashes with other major live events.

Why is the network shifting times?

Fall premieres and live sports routinely pressure CBS’s primetime grid. As Big Brother 27 barrels toward its conclusion in late September, those conflicts intensify. That’s why the series is leaning on later start times, longer episodes, and one-off specials to keep momentum high while sidestepping heavy hitters, according to SoapCentral’s breakdown.

How to keep up without missing key moments

  • Double‑check local listings on Sundays, Wednesdays, and Thursdays—times may slide later than usual.
  • Follow official show updates, since changes can be announced close to airtime.
  • Expect live‑feed disruptions on nights with schedule tweaks or special events.

These adjustments can affect when spoilers circulate and how endgame momentum builds. If you’re used to the show’s standard rhythm, don’t assume it holds through finale night.

Bottom line

Big Brother 27 is still on three nights a week, but late‑September brings a meaningful schedule shake‑up—delays, longer episodes, and a later‑than‑usual finale time. Plan around the new times so you catch every alliance crack, veto gamble, and final vote.
